Question

A random sample of 36 observations is drawn from a population with a mean egun to 25 and A standard deviation equal to 6. Complete parts a through below a. Glve the mean and standard deviation of the repeated samping distribution : - 25 (Type inlagers or decimals. b. Describe the shape of the sampling darbution of R. Does this answer depend on the sample size? Choose the correct answer below A. The shape is that of a normal distribution and depends on the sample size B. The shape is that of a unorm wbuon and does not depend on the samples OC. The shape is that of a normal distribution and does not depend on the sample size D. The shape is that of a uniform distribution and depends on the same size. a. Calculate the standard roma -core corresponding to a value of R-22.9. 2-2.1 Type an Integer or a decimal) d. Calculate the standard romalz-score corresponding to a value of i=273 2-2.3 (Type an integer or a decimal) Find P(x<229) PG<229) - Round to four decimal places as needed

Help with part e.
