Determine the sampling distribution of the sample mean for samples of size 3. The mean of the sample mean is μx= ?The standard deviation of the sample mean is σx= ?b. Determine the sampling distribution of the sample mean for samples of size 12. The mean of the sample mean is μx= ?The standard deviation of the sample mean is σx= ?d. Determine the percentage of all samples of three men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.10 kg.e. Determine the percentage of all samples of twelve men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.10 kg.

Religion and Theology Assignment Writing ServiceA coin shows heads with probability p when tossed. The coin is tossed repeatedly until both heads and tails has appeared. Let X be the total number of tosses. Let Y be the indicator function of the event that the first toss is heads. (i) Find E(X|Y = 1) and E(X|Y = 0). (i) Hence calculate E(X). (ii) What is the probability that the last toss is heads?

The diameter of the Douglas fir tree is measured at a height of 1.37 meters. The following data represent the

The diameter of the Douglas fir tree is measured at a height of 1.37 meters. The following data represent the diameter in centimeters of a random sample of 12 Douglas firs in the western Washington Cascades. (a) Obtain a point estimate for the mean and standard deviation diameter of a Douglas fir tree in the western Washington Cascades. (b) Because the sample size is small, we must verify that the data come from a population that is normally distributed and that the data do not contain any outliers. The figures show the normal probability plot and boxplot. The correlation between the tree diameters and expected z-scores is 0.982. Are the conditions for constructing a confidence interval for the population mean diameter satisfied? c) Construct a 95% confidence interval for the mean diameter of a Douglas fir tree in the western Washington Cascades. Interpret this interval.

1) Residents living on or near North Main Street in Cedar City are concerned about the speed of vehicles traveling

1) Residents living on or near North Main Street in Cedar City are concerned about the speed of vehicles traveling on that road. Drivers seem to have a tendency to drive at high speeds on their way out of and into town, even though the speed limit is 45 mph. Cedar City Police officers often record the speeds of the vehicles and ticket those who are found to be speeding. A file titled Speeding.xls The police department would like to know if the average speed traveled by all drivers on Main Street is greater than 5 mph above the speed limit (i.e. greater than 50 mph) with ? = 0.01. We will conduct this hypothesis test by completing all six steps. a. Define the parameter of interest, the null hypothesis, and the alternative hypothesis for this situation. b. State the significance level. c. Compute the test statistic. d. Compute the p-value. e. Interpret the p-value you computed in part d in the context of the problem. f. Make a statistical decision. g. Provide an interpretation of your decision in the context of the problem. Remember that we interpret these in terms of the alternative hypothesis. 2) Some people argue that an average speed is not a great indicator of a speeding problem. Instead, they think the proportion of cars that speed is far more important. If more than 35% of vehicles are driving faster than 5 mph over the speed limit (driving faster than 50 mph), this could indicate a speeding problem. Conduct an appropriate hypothesis test if more than 35% of vehicles on North Main Street are going faster than 50 mph at the 0.01 significance level. You can decide whether to make the decision using critical values and a rejection region or using a p-value. Show all steps in the test. Hint: to obtain ?̂, you’ll need to look back at the data file to find the sample proportion of vehicles who were found to be traveling faster than 50 mph (not equal to 50 mph). It is easiest to count this manually. 3) Summarize your findings from the previous two problems. Did the test you performed in problem 1 seem to indicate there was a speeding problem? How about the test performed to problem 2? If these were different why was that the case? 2 – 3 sentences should be enough here.

The Laborers in the Vineyard – Matthew 20:1-1620 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 “For the kingdom of heaven is like a landowner who went out early in the morning to hire laborers for his vineyard. After agreeing with the laborers for the usual daily wage, he sent them into his vineyard. When he went out about nine o’clock, he saw others standing idle in the marketplace; and he said to them, ‘You also go into the vineyard, and I will pay you whatever is right.’ So they went. When he went out again about noon and about three o’clock, he did the same. And about five o’clock he went out and found others standing around; and he said to them, ‘Why are you standing here idle all day?’ They said to him, ‘Because no one has hired us.’ He said to them, ‘You also go into the vineyard.’ When evening came, the owner of the vineyard said to his manager, ‘Call the laborers and give them their pay, beginning with the last and then going to the first.’ When those hired about five o’clock came, each of them received the usual daily wage. Now when the first came, they thought they would receive more; but each of them also received the usual daily wage. And when they received it, they grumbled against the landowner, saying, ‘These last worked only one hour, and you have made them equal to us who have borne the burden of the day and the scorching heat.’ But he replied to one of them, ‘Friend, I am doing you no wrong; did you not agree with me for the usual daily wage? Take what belongs to you and go; I choose to give to this last the same as I give to you. Am I not allowed to do what I choose with what belongs to me? Or are you envious because I am generous?’ So the last will be first, and the first will be last.” 1) Summarize the events. 2) What is the moral of the story/point it seems to be making?3) Christological Twist: Jesus is also inviting his listeners to see him, his death and resurrection and his salvation as at the center of the parable. Please explain how the parable could be read as about Christ’s death, taking away sin, and resurrection.
