In IQ test was given to a simple random sample of 67 students at a certain college. The sample mean score was 106.4. Scores on this test are known to have a standard deviation of o = 10. It is desired to construct a 90% confidence interval for the mean IQ score of students at this college. Part: 0 / 6 Part 1 of 6 (a) What is the point estimate? The point estimate is X Part: 1 / 6 Part 2 of 6 (b) Find the critical value. The critical value is X Part: 2 / 6Part 3 of 6 (c) Find the standard error. Round to four decimal places. The standard error is X Part: 3 / 6 Part 4 of 6 (d) Find the margin of error. Round to two decimal places. The margin of error is X Part: 4 / 6 Part 5 of 6 (e) Construct the 90% confidence interval. Round to one decimal place. The confidence interval is XPart 5 of 6 (e) Construct the 90% confidence interval. Round to one decimal place. The confidence interval is X Part: 5 / 6 Part 6 of 6 (f) Is it likely that the population mean u is greater than 100? (Choose one) it (Choose one) V likely that the population mean u is greater than 100. Xx=44, n=97, confidence level 98% Part: 0 / 3 Part 1 of 3 (a) Find the point estimate.
