Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 47.5 miles per hour. C Speed (miles per hour) Frequency 42 - 45 46-49 50 - 53 54 - 57 58 -61 22 16 4 Good Chro The mean of the frequency distribution is miles per hour. (Round to the nearest tenth as needed.) E Which of the following best discribes the relationship between the computed mean and the actual mean? O A. The computed mean is not close to the actual mean because the difference between the means is more than 5%. Micro Edg O B. The computed mean is not close to the actual mean because the difference between the means is less than 5%. O C. The computed mean is close to the actual mean because the difference between the means is less than 5%. PD O D. The computed mean is close to the actual mean because the difference between the means is more than 5%.

A study was conducted to test whether marijuana use impacts your short-term memory. A simple random sample of college students that do NOT use marijuana was taken, and given a memory test in which they were shown items in a particular order then asked to recreate that ordering. A second simple random sample was taken of college students that use marijuana 4 - 7 days per week, and they were given the same memory test.  A higher score on the memory test indicates better memory recall.  μ1μ1 indicates the population mean memory recall score for non-users. μ2μ2 indicates the population mean memory recall score for marijuana users. The 90% confidence interval for the difference of means was found to be: -6.4 < μ1−μ2μ1-μ2  < 8.2  Can we support the claim that marijuana users have less short-term memory than non-users?    Yes or No?   Why or why not?
