Part 1: Function to generate sampling distribution of the sample meanWrite a function called samp.dist.mean, SUCch that:• Takes as inputs: i) a population vector ( pop ), ii) the number of samples ( n, lower-case) to draw, and iii) the number of experiments toconduct (call this variable is k ).• In the body of the function: i) for a given sample size n, uses the function sample.mean (with out.sample=FALSE ) to obtain the samplemean for each experiment (i.e., for k = 1, 2,... , K).• Outputs: returns a vector of length K with the sample means obtained from the K experiments.

Q2. Answer the following two questions under the assumption of normal populations with equal vari- ances. (a) The following are the numbers of sales which a random sample of nine salesmen of industrial chemicals in California and a random sample of six salesmen of industrial chemicals in Oregon made over a fixed period of time: (California) x; : 40, 46, 61, 38, 55, 63, 36, 60, 51 (Oregon) y; : 33, 62, 44, 54, 23, 42 Using s 5% level of significance, test whether or not California salesmen are more efficient in general. Write down the null and alternative hypothesis first. (b) Suppose that we wish to investigate whether males and females earn comparable wages in a cer- tain industry. Sample data show that 14 randomly surveyed males earn on the average $213.5 per week with a standard deviation of $16.5, while 18 randomly surveyed females earn on the average $194.1 per week with a standard deviation of $18.0. Let µi denote the average wage of males and 42 the average of females. Using a…

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.

Express the alternative hypothesis in symbolic form. A psychologist claims that the mean amount of time (in hours) that females spend in talk therapy is more than that of men. Assume that two samples are independent. Let the female talk therapy times be the first population and the male talk therapy times be the second population.
