assuming that the rate of 27% is correct, find the probability that 433 or more of the 1456 adults have sleepwalked. b) is that result of 433 or more significantly high? c) What does the result suggest about the rate of 27%?

Based on a smartphone​ survey, assume that 57​% of adults with smartphones use them in theaters. In a separate survey of 264 adults with​ smartphones, it is found that 149 use them in theaters. a. If the57% rate is​ correct, find the probability of getting 149 or fewer smartphone owners who use them in theaters. b. Is the result of 149 significantly​ low?

Assume that when adults with smartphones are randomly selected, 48% use them in meetings or classes. If 6 adult smartphone users are randomly selected, find the probability that exactly 3 of them use their smartphones in meetings or classes. ... The probability is (Round to four decimal places as needed.) Next

Assume that when adults with smartphones are randomly​ selected, 43% use them in meetings or classes. If 14 adult smartphone users are randomly​ selected, find the probability that fewer than 3 of them use their smartphones in meetings or classes. The probability is?

Assume that when adults with smartphones are randomly​ selected, 46​% use them in meetings or classes. If 6 adult smartphone users are randomly​ selected, find the probability that exactly 3 of them use their smartphones in meetings or classes.

Based on a smartphone survey, assume that 51% of adults with smartphones use them in theaters. In a separate survey of 248 adults with smartphones, it is found that 110 use them in theaters. a. If the 51% rate is correct, find the probability of getting 110 or fewer smartphone owners who use them in theaters. b. Is the result of 110 significantly low? a. If the 51% rate is correct, the probability of getting 110 or fewer smartphone owners who use them in theaters is (Round to four decimal places as needed.) b. Is the result of 110 significantly low? v because the probability of this event is v than the probability cutoff that corresponds to a significant event, which is Question Viewer Enter your answer in the answer box. ?
