Example 3.6. Take a random sample of size n from an exponential distri- bution with rate parameter XA. 1. Derive an exact 95% confidence interval for X. 2. Suppose your sample is of size 9 and has sample mean 3.93. (a) What is your 95% confidence interval for λ? (b) What is your 95% confidence interval for the population mean? 3. Repeat the above using the CLT approximation (rather than an eract interval

Problem:
Obtain a random sample size n of at least 30 on a
random variable of your choice. Plot the frequency histogram, and
compute the mean, standard deviation, and skew. Use the relative
frequency histogram to determine the interval probability,
cumulative probability, and exceedence probability of values of
your choice (choose any valuss of your choice) Use the handout, in
photos below, which contains precipitation data for College Station
to guide you.
Illustrative example:(Ref. exampl The values of annual precipitation,x...
