Please no written by hand solution and no img 1) A medical research team is investigating the benefits of a new surgical treatment. The standard recovery time from the existing surgery is a mean of 96 hours. In a random sample of 40 patients undergoing the new treatment, the mean recovery time was 90 hours with a standard deviation of 12 hours. Is there enough evidence at the 1% significance level to show that the recovery from the new surgical treatment is shorter than 96 hours? c) What’s the significance (α) level?           d) What is the test statistic? Round to three decimal places.           e) What is the p-value? Round to three decimal places.
