See picture for questions A and b Michael, a nurse manager at a local hospital, wanted to know more about the hospital's full-time nurses. He polled 12 nurses at random who work full-time at the hospital. The findings in the poll were that these nurses take, on average, 5.5. sick days per year, that 50% of them would prefer a four-day work schedule, and that 8 of them are married. Michael didn't know that the top hospital administrators had already surveyed all nurses who work full-time at the hospital. In that survey, it was found that the nurses take, on average, 5.7 sick days per year, that 61% of them would prefer a four-day work schedule, and that 77 of them are married.

Use the following information for the question. A group of home gardeners want to test whether the type of soil used to grow heirloom tomatoes has an effect on the number of tomatoes harvested. Gardeners randomly assigned tomato plants to be grown in soil with no fertilizer, commercial plant food, and homemade compost. All other growing conditions were kept the same. Forty plants were assigned to each group. At the end of the growing season the number of tomatoes harvested was counted. Assume that all other conditions for the ANOVA test have been met. One-way ANOVA F=0.762135 P=0.5202354 Factor df-2 SS=710.349206 MS=355.174603 Using the test results provided, test the hypothesis that soil treatment affects the number of tomatoes harvested. Use a significance level of 5%. Choose the correct decision regarding the null hypothesis and correct conclusion. O Reject Ho. We can conclude that the treatment of the soil affects the number of heirloom tomatoes harvested. O Reject Ho- We can…
