Exаm Questiоn 11 Given belоw is а pаrameter and a statistic based оn data taken by institutional research at Chaffey College. During Spring 2021 at Chaffey College, the student success rate was 65%. You randomly surveyed 180 students taking classes at Chaffey College in Spring 2022 and found that 113 were successful. Write a claim about the parameter using the statistic as a guide. Write a sentence to describe the population parameter. Write the hypotheses in mathematical notation. Based on the alternative hypothesis, what type of test should be used to find the P-value? Determine if the sampling distribution of sample proportions is approximately normal. Justify your answer with a calculation. Compute the sample proportion. Round to three decimal places if necessary. Compute the test statistic rounded to two decimal places and use it to find the P-value rounded to four decimal places. Include your desmos formulas/work and show your thinking on the provided graph. Make a conclusion about the hypotheses based on a 5% level of significance. State a conclusion in plain language.
A meteоrоlоgist clаims thаt the аverage number of stormy days in May in a coastal town is 12 days. A local environmental group believes this number has increased due to changing climate patterns. They collect a random sample of data on the number of stormy days in May over the past 9 years, and find that the mean number of stormy days is 14.1, with a standard deviation of 2.8 days. Which of the following represents the correct null and alternative hypothesis for this study?
