The bar graph shows the results of spinning a spinner 100 times. Use the bar graph to find the experimental probability of not spinning a 5. A bar graph, titled Spinning a Spinner. Horizontal axis shows number spun. Vertical axis shows times spun. The first bar is labeled 1. It ends at 20. The second bar is labeled 2. It ends at 18. The third bar is labeled 3. It ends at 22. The fourth bar is labeled 4. It ends at 21. The fifth bar is labeled 5. It ends at 19.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
