In a large city, 70% of people own a cell phone. A sociologist wishes to study the impact cell phones have on society. To get started, the sociologist randomly samples 45 people in the city. Use a calculator to find the probability that of those 45 people sampled, between 33 and 36 of them own a cell phone. Round your answers to two decimal places.

Is the probability of a bowler rolling a strike higher after he has thrown four consecutive strikes? Researchers investigated the phenomenon of a "hot hand" in bowling. Frame-by-frame results were collected on 43 professional bowlers. For each bowler, the researchers calculated the proportion of strikes rolled after bowling four consecutive strikes and the proportion after bowling four consecutive nonstrikes. The data on 4 of the 43 bowlers are shown in the accompanying table. Complete parts a and b. Click the icon to view the data table. Click the icon to view a table of critical values for the Wilcoxon signed rank test. a. Do the data on the sample of four bowlers provide support for the "hot hand" theory in bowling? Explain. (Let the differences be After Four Strikes - After Four Nonstrikes.) Set up the null and alternative hypotheses. Ho: : The distribution of the proportion of strikes rolled after bowling four consecutive strikes is Ha: : The distribution of the proportion of…
