a. Use theone-mean z-interval procedure to find a confidence interval for the mean of the population from which the sample was drawn.

The confidence interval is from

32.0

32.0 to

36.0

36.0.

(Type integers or decimals rounded to one decimal place asneeded.)

b. Obtain the margin of error by taking half the length of the confidence interval.

What is the length of the confidenceinterval?

nothing

(Type an integer or decimal rounded to one decimal place asneeded.)
