Question

An avid birdwatcher wants to know if the number of goslings per goose in his lake differs from the regional average of 2.58. He takes a random sample of geese, conducts a hypothesis test of

H0: μ = 2.58 vs.
Ha: μ ≠ 2.58,

and obtains a p-value of 0.013.

(a) What should you expect of a 95% confidence interval constructed from his data?
 ---- The interval should contain 2.58 The interval should not contain 2.58 The interval should contain 0 The interval should not contain 0 We cannot say anything about the interval because  ---- the p-value is not less than the corresponding alpha. the p-value is less than the corresponding alpha. we cannot make a conclusion about a confidence interval just from a hypothesis test. .
(b) Given his sample size what 74, what critical value would the birdwatcher use to make the 95% confidence interval?  (3 decimal places)

(c) The birdwatcher's friend says his geese have an average of 3.88 goslings, and the birdwatcher wants to know if that would be a reasonable conclusion for his geese, as well. What could you predict about whether or not a 98% confidence interval built from this data would contain 3.88?
The interval should contain 3.88 since the p-value is less than the corresponding alpha.The interval should not contain 3.88 since the p-value is less than the corresponding alpha.    Without constructing the interval, we could not tell.The interval should contain 3.88 since the p-value is more than the corresponding alpha.The interval should not contain 3.88 since the p-value is more than the corresponding alpha.
