A professor wants to estimate how long students stay connected during twohour online lectures. From a random sample of 21 students, the mean stay time was 92 minutes with a standard deviation of 11 minutes. Assuming the population has a normal distribution, develop a 99% confidence interval estimate for the population mean by determining the following values: 1. a) Point Estimate = :1 l3] Elf: :1 Signicance level {or} = :1 c] Determine the critical value rounded to 3 decimal places. Enter a positive value. [3 decimal places] Critical value = C} d] [3 decimal places] Standard Error = e) [1 decimal place] Margin of Error 2 :1 f] [1 decimal place] Lower Confidence Limit = C] g] [1 decimal place] Upper Confidence Limit 2 C] 2. Should we reject a claim that the population meanr pi = 103 minutes? Why? Select an answer v 3. If the sample size increases, what will be the effect on the margin of error? Select an answer v 2. Should we reject a claim that the population mean, # = 103 minutes? Why? Select an answer Select an answer Yes. Because 103 lies outside the confidence limits 3. No. Because 103 lies within the confidence limits he effect on the margin of error? Yes. Because 103 lies within the confidence limits No. Because 103 lies outside the confidence limits3. If the sample size increases, what will be the effect on the margin of error? Select an answer Select an answer The margin of error will not change. ues The margin of error will decrease. ge instructor The margin of error will increaseIn conducting a left-tailed hypothesis t-test with df = 21, the test statistic was found to bet = -1.651. For which of the following values of o is the result statistically significant (that is, for which o should Ho be rejected)? Select all that apply: Da = 0.1 Da = 0.005 Da = 0.025 Da = 0.05 Da = 0.01 None of the above
