Question

Transcribed Image Text:A dietician read in a survey that 69.22% of adults in the U.S. do not eat breakfast at least 3 days a week.
She believes that a larger proportion skip breakfast 3 days a week. To verify her claim, she selects a
random sample of 71 adults and asks them how many days a week they skip breakfast. 46 of them report
that they skip breakfast at least 3 days a week. Test her claim at a = 0.10.
The correct hypotheses would be:
Ho:p ≤ 0.6922
HA:P 0.6922 (claim)
O Ho: p > 0.6922
HA:P < 0.6922 (claim)
O Ho: p = 0.6922
HA P0.6922 (claim)
Since the level of significance is 0.10 the critical value is 1.282
(round to 3 places)
The test statistic is:
The p-value is:
(round to 3 places)
