The following random sample was selected from a normal distribution: 4, 6, 3, 5, 9, 3. a. Construct a 90% confidence interval for the population mean. b. Construct a 95% confidence interval for the population mean. c. Construct a 99% confidence interval for the population mean. d. Assume that the sample mean x and sample standard deviation s remain exactly the same as those you just calculated but are based on a sample ofn= 25 observations rather than n = 6 observations. Repeat parts a-c. What is the effect of increasing the sample size on the width of the confidence intervals? n3D %3D e. Use Rejection region to test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, u<6. Use a = .05. f. Use p-Value to test the null hypothesis that the mean of the population is 6 against the alternative hypothesis, u #6. Use a = .05.
