Emily walks every day, and she keeps a record of the number of miles she walks each day. The histogram and five-number summary below were created from the recorded miles for a random sample of 25 of the days Emily walked. Frequency 10 1 2 3 4 5 6 7 Miles Walked 8 Minimum Q1 Median Q3 Maximum 1.4 2.6 3.25 3.8 7.5 On one of the 25 days in the sample, Emily walked 7.5 miles. From the histogram, it appears that the value 7.5 might be an outlier relative to the other values. Two methods are proposed for identifying an outlier in a set of data. (a) One method for identifying an outlier is to use the interquartile range (IQR). An outlier is any number that is greater than the upper quartile by at least 1.5 times the IQR or less than the lower quartile by at least 1.5 times the IQR. Does such a method identify the value of 7.5 miles as an outlier for Emily's set of data? Justify your answer.

South Dakota prices vary $350,000: $400,000:$400,000:$425,000:$429,000: $440,000: $560,000: $585,000,: $585,000: $785,000 : $1,300,000. We found the following Mean = 569000 SD = 272703.1353 T score = .7113 P Value = .4932 We failed to reject the hypothesis. What is a 95% confidence interval and how would you create one for the population average price? What would it look like. How does this related to Central limit therorem? If you had a margin of error of $13,000 how large of sample would you need with a 90% confidence interval using the given tscore.

Does the mean represent the center of the data? O A. The mean represents the center. O B. The mean does not represent the center because it is not a data value. O C. The mean does not represent the center because it is the largest data value. O D. The mean does not represent the center because it is the smallest data value. O E. There is no mean cost.
