How would you use a random number tabke to get a random sample of size 15 from a population of size 960? Assume that each measurement in the sameple must come from a different population item. Suppose the first line of the random number table reads

calculate the mean and ss for each of the following sample numbers 1,3,4,0

About 7% of the population has a particular genetic mutation. 100 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 100. (Round to 2 decimal places if possible.)

A gym manager is interested in whether the ‘beginner’ and ‘expert’ climbing walls (that were of the same height) at her facility are actually different from each other. To test this, she decides to look at the time it takes people to reach the top of both walls. She recruits 25 students and has them each climb both walls and looks for differences between the ‘beginner’ wall climbing times and the ‘expert’ wall climbing times.   Select one: a. single sample t-test b. one-way ANOVA c. paired samples t-test d. z-test e. factorial ANOVA  f. t-test independent means

Please give an answer with a calculation and give an explanation of the correct and incorrect option.

When dragons on the fictional planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 32% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 48 of the dragon eggs to incubate. Consider all the possible samples of 48 dragon eggs. Round answers to 4 decimal places. a) Compute the mean number of yellow eggs in samples of 48 eggs? (that is the same as asking for the expected value of the number of yellow eggs)mean =  b) Compute the standard deviation in the number of yellow eggs in samples of size 48?standard deviation =  c) Compute the variance in the number of yellow eggs in samples of size 48?variance =

Week 10. Question 6 In a research report, suppose a researcher states that they ‘randomly’ stopped passers-by in a shopping centre to get responses for their survey. Explain why this process is not truly random.

Generate 10000 instances of a poisson (10) random variable and then compute the sample mean, sample variance, and sample standard deviation.

USE EXCEL to solve this problem. Thanks.
