To determine the effect of 100% nitrate on the growth of pea plants, several specimens were planted and then watered with 100% nitrate every day. At the end of two weeks, the plants were measured. Here are data on seven of them: Assume that these data are a random sample from a normal distribution N(μ, σ2).

(a) Find the value of a point estimate of μ.

(b) Find the value of a point estimate of σ.

(c) Give the endpoints for a 90% confidence interval for μ.
