Answer #1

a)

df = n - 1 = 18 - 1 = 17

t critical value at 0.05 significance level with 17 df = 2.110

95% confidence interval for is

- t * S / sqrt(n) < < + t * S / sqrt(n)

5061 - 2.110 * 1751 / sqrt( 18) < < 5061 + 2.110 * 1751 / sqrt( 18)

4190.17 < < 5931.83

95% CI is ( 4190.17 , 5931.83 )

b)

We need to assume that population is normally distributed.

Sue, a starting player for a major college basketball team, made only 38% of her free throws last year. During the summer she worked on developing a softer shot in the hope of improving her free-throw accuracy. In the first eight games of this season Sue made 22 free throws in 40 attempts. Assume that these 40 attempts represent a random sample of free throws. Let p be the probability of making each free throw she shoots this season. Does...
