Pleаse nоte thаt this questiоn cоnsists of three pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. In one of the Southern states, a utility company wants to study the true proportion of households that have installed solar panels. The company takes a random sample of 110 households and asks whether they have solar panels installed on their property. Of the sampled households, 18 reported having solar panels. Find a 95% confidence interval for the true proportion of households in the state that have installed solar panels. Interpret the calculated interval in the context of the problem. The utility company believes that about a quarter of households in the state have installed solar panels. Based on the interval in part 1, is the company's belief reasonable? Explain.
Pleаse nоte thаt this questiоn cоnsists of six pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. A gardener wants to test whether the average number of tomatoes produced by a plant during a growing season is different from 25 tomatoes. The gardener randomly selects 10 tomato plants and records the number of tomatoes produced by each plant. For this sample, the mean is 26.7 tomatoes and the standard deviation is 2.81 tomatoes. Set up appropriate null and alternative hypotheses for testing the question posed by the gardener. Are the conditions to carry out the above stated test are satisfied? If the conditions are satisfied, explain how they were satisfied for this problem rather than simply giving a "yes" or "no" answer. Calculate the test statistic. Show your calculations. Find the rejection region for the test defined in part 1. Use 5% significance level. It is not sufficient to provide just the critical value. Clearly state the rejection region. Write the final conclusion in the context of the problem. Based on the decision you made in part 5, which error: type I or type II is possible? Explain.
