The standard deviation of the given the data (14, 13, 16, 9, 3} is ♦ If the average American male is 5'10" and the standard deviation is 3", then Yao Ming who is 7'6" is within ◆ standard deviations of the mean? An outlier is an extreme value that is significantly less or more than the rest of the data. In the data below take out the outlier, then calculate using a statistics calculator or spreadsheet, the standard deviation of the heights of 15 soda cans. {92.8, 92.8, 92.9, 92.9, 92.9, 92.8, 92.7, 92.9, 92.1, 92.7, 92.8, 92.9, 92.9, 92.7, 92.8} Round to the nearest 100th. Answer:

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 47.1 miles per hour. 58 - 61 Speed (miles per hour) Frequency 42 - 45 29 46 - 49 14 50 - 53 54 - 57 3 ..... The mean of the frequency distribution is miles per hour. (Round to the nearest tenth as needed.) Which of the following best discribes the relationship between the computed mean and the actual mean? O A. The computed mean is close to the actual mean because the difference between the means is more than 5%. O B. The computed mean is not close to the actual mean because the difference between the means is more than 5%. O C. The computed mean is close to the actual mean because the difference between the means is less than 5%. O D. The computed mean is not close to the actual mean because the difference between the means is less than 5%.

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.  POP2014: 3072, 1989, 3794, 2689, 3211, 3722, 4385, 4009, 7598, 3862, 3097, 2726, 4881, 4157, 2570, 2512, 2518, 4863, 4147, 7139, 6067, 6819, 3705, 3239, 3824, 4977, 2576, 2940, 9791, 5231, 5634, 5337, 4205, 3888, 5562, 3335, 3770, 1808, 2045, 1532, 5420, 4993, 6109, 4377, 5424, 4976, 4507, 3738, 2827, 3485, 1559, 5199, 4702, 3971, 3803, 3356, 4670, 3816, 5477, 4760, 3126, 3630, 3755, 3795, 2578, 3382, 4005, 2442, 6096, 3799, 3843, 3836, 6046, 6431, 3561, 3142, 4829, 5058, 2471, 6119, 3523, 3094, 3146, 3356, 2618, 2366, 4266, 4016, 6080, 1554, 6878, 3645,…

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 57.4 degrees. The mean of the frequency distribution is ​(Round to the nearest tenth as​ needed.)

A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1539 and the standard deviation was 315. The test scores of four students selected at random are 1940, 1290, 2240, and 1420. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1940 is. (Round to two decimal places as needed.) The Z-score for 1290 is. (Round to two decimal places as needed.) The Z-score for 2240 is. (Round to two decimal places as needed.) The Z-score for 1420 is. (Round to two decimal places as needed.) Which values, if any, are unusual? Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. The unusual value(s) is/are. CD (Use a comma to separate answers as needed.) OB. None of the values are unusual.
