A sample of size n = 100 is used to test H0 : μ ≤ 20 versus H1 : μ > 20. The value of μ will not have practical significance unless μ > 25. The population standard deviation is σ = 10. The value of X¯¯¯ is 21. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

(a) Assume the sample size is n = 100. Compute the P-value. Show that you do not reject H0.
(b) Assume the sample size is n = 1000. Compute the P-value. Show that you reject H0.
(c) Do you think the difference is likely to be of practical significance?
(d) Explain. Explain why a larger sample can be more likely to produce a statistically significant result that is not of practical significance.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
