Colored Wax & Co. sells candles with a mean burn time of 50 minutes. The company wants to test its candles' burn time against a competitor's candles. Researchers from Colored Wax & Co. randomly select 25 candles from its competitor for testing. From previous research, the staff of Colored Wax & Co. knows that σ = 12.5.
Suppose the mean burn time is actually 53 minutes. Find the possibility of a Type II error (β) and the power of the test.

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
