Answer the last part The 90% confidence interval is(125.74,134.26)The 95% confidence interval is(124.93,135.07) Construct a 95% confidence interval for the population mean.The 95% confidence interval is (124.93, 135.07 ).(Round to two decimal places as needed.)Interpret the results. Choose the correct answer below.O A. With 90% confidence, it can be said that the sample mean price lies in the first interval. With 95%confidence, it can be said that the sample mean price lies in the second interval. The 95% confidenceinterval is wider than the 90%.O B. With 90% confidence, it can be said that the population mean price lies in the first interval. With 95%confidence, it can be said that the population mean price lies in the second interval. The 95% confidenceinterval is narrower than the 90%.O C. With 90% confidence, it can be said that the population mean price lies in the first interval.

Math 310-Assignment 3- Question * Among various ethnic groups, we want to construct a 95% confidence interval for the mean height of male Swedes. 25 males Swedes are surveyed. The sample mean is 71 inches. The sample standard deviation is 2.8 inches. Assuming normality of height of male Swedes, the 95% confidence interval for the mean height is: O [69.8441, 72.1558] [68.111, 72.732] [68.764, 72.866] O [69.001, 72.426] Question
