A large home improvement store is considering expanding its selection of moving products, such as cardboard boxes and packing tape. The store constructs a 90% confidence interval to estimate the proportion of all customers who have moved houses at least once in the last five years. In the random sample of 620 customers, 201 (32.4%) replied that they had moved at least once in the last five years. The sample yielded the 90% confidence interval (0.293, 0.355) for the proportion of all customers who have moved in the past five years. Sheldon, an employee who wishes to expand the selection of moving products, claims that more than 1 in 4 customers have moved in the past five years. Zachary, another employee, urges Sheldon to be bolder in his claim and say that more than 1 in 3 customers have moved in the past five years. Based on the confidence interval, which employee’s claim is plausible? Sheldon’s claim is plausible, but Zachary’s is incorrect.
Both Sheldon and Zachary have made plausible claims.
Sheldon’s claim is incorrect, but Zachary’s claim is correct.
Sheldon’s claim is plausible, but it is not certain that Zachary’s is plausible.

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
