You are tracking Chipotle Mexican Grill's stock price, attempting to figure out a good price point for entry into the market. You look at 43 random days over the course of a few months and see that the closing price has an average of $349.9 with a standard deviation of $19.258. You construct a 95% confidence interval for the average stock price to be (343.973, 355.827). what is the appropriate interpretation of this interval?
A university is comparing the hourly wages of students who completed a Master's Degree to students who only completed a Bachelor's Degree. Of the students surveyed, 70 had a Master's degree and 88 had a Bachelor's Degree only. The average hourly rate for those with a Master's was $41.398 (SD = $4.108). Among the graduates with a Bachelor's degree, the average hourly rate was $25.116 (SD = $7.426). If a 90% confidence interval is calculated to estimate the difference between the average hourly rates for each type of graduate, what is the margin of error?
