Question

A corresponding relationship between confidence intervals and two-tailed hypothesis tests also is valid for other parameters, such as p, ?₁ − ?₂, or p₁ − p₂, which we will study in later sections.) Whenever the value of k given in the null hypothesis falls outside the c = 1 – α confidence interval for the parameter, we reject H₀. For example, consider a two-tailed hypothesis test with ? = 0.01 and

H₀: ? = 21
H₁: ? ≠ 21

A random sample of size 30 has a sample mean x = 22 from a population with standard deviation ? = 3.

(a) What is the value of c = 1 − ??

Using the methods of Chapter 7, construct a 1 − ? confidence interval for ? from the sample data. (Round your answers to two decimal places.)
