1. In a random sample of 8 ​people, the mean commute time to work was 34.534.5 minutes and the standard deviation was 7.27.2 minutes. A 9090​% confidence interval using the​ t-distribution was calculated to be left parenthesis 29.7 comma 39.3 right parenthesis(29.7,39.3). After researching commute times to​ work, it was found that the population standard deviation is 9.19.1 minutes. Find the margin of error and construct a 9090​% confidence interval using the standard normal distribution with the appropriate calculations for...

1. In a random sample of 23 people, the mean commute time to work was 32.2 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean mu. What is the margin of error of mu? Interpret the results. Round to one decimal place as needed.

Q: When time series exhibit a trend the first differences should be used to fit a ARIMA model. True or False and Why? Q: Randomized experimental designs are considered the gold standard because the influence of confounders on the treatment effect estimation is limited through the process of random selection into treatment group and control group, so it leads to an unbiased estimation of the treatment effect. True or False and Why?
