LORETTA STONE 1/14 Question 2 of 8, Step 2 of 2 Correct Steve believes that his wife's cell phone battery does not last as long as his cell phone battery. On seven different occasions, he measured the length of time his cell phone battery lasted and calculated that the mean was 16.3 hours with a standard deviation of 5.5 hours. He measured the length of time his wife's cell phone battery lasted on eleven different occasions and calculated a mean of 21.6 hours with a standard deviation of 2.7 hours. Assume that the population variances are the same. Let Population 1 be the battery life of Steve's cell phone and Population 2 be the battery life of his wife's cell phone.

O Point Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error: 0.05; confidence level 90%; p and q unknown n = (Round up to the nearest integer.)
Explanation and steps
You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately 82%. You would like to be 99% confident that your estimate is within 5% of the true population proportion. How large of a sample size is required?

Hi, may you please help me with the following: The purpose of this assignment is to apply hypothesis tests to the case of Bayview University. Use the dataset below and read the case thats attached, use descriptive statistics to summarize the data and comment on your findings. Answer the following 3 questions. Develop 95% confidence interval for the proportion of all students, the proportion of male students, and the proportion of female students who were involved in some type of cheating. Conduct a hypothesis test to determine whether the proportion of business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions by the Chronicle of higher education.
