A distance AB is observed repeatedly using the same equipment and procedures, and the results, in meters, are listed in Problems 3.7 through 3.10. Calculate (a) the line's most probable length, (b) the standard deviation, and (c) the standard deviation of the mean for each set of results. 3.7 65.401, 65,400, 65.402, 65.396, 65,406, 65.401, 65.396, 65.401, 65.405, and 65.404. 3.8 Same as Problem 3.7, but discard only one 65.396 observation. 3.9 Same as Problem 3.7, but discard both 65.396 observations. 3.10 Same as Problem 3.7, but include two additional observations, 65.402 and 65.405.
3. The average (or mean) amount of hours spent on social media per day is 2 hours and the standard deviation is 2 hours. Calculate the z scores for the following individual scores: Person 1 (X) = 1 hour, z = Person 2 (X) = 3 hours, z= Person 3 (X) = 4 hours, z=
If actual period demand varies from the forecast by more than 3MAD, this indicates: there is 3% chance that the forecast is wrong. there is a 98% chance that the forecast is wrong. there is a 97% chance that the forecast is wrong. there is a 3% chance that the forecast is correct Moving to the next question prevents changes to this answer:
In the past, the mean age of consumers of a product was 38 years. Recently the product has been drastically changed. In order to determine whether there has been a change in the mean age of the product consumers, a sample of 16 consumers is selected. The mean age in the sample is 33 years and the standard deviation in the sample is 10 years. Let u = the mean age of the current product (Problem Set #7) consumers. The value of the test statistic is Oa. -2.00 O b.-1.60 OC .0.8 O d. 4.21
The standard deviation for the distribution set is in problem 33 isA. P2, 700B. P2,750C. P2,754D. P2,754.0731. The variance of 19, 21, 23, 25 and 27 is 8. The variance of 14, 16, 18, 20 and 22 is:A. Greater than 8B. Less than 8C. 8D. 332. If standard deviation of the values 2, 4, 6, 8 is 2.236, then the standard deviation ofthe values 4, 8,12, 16 is:A. 0B. 4.472C. 4.236D. 2.236
4. A very large population has a mean of 180 and a standard deviation of 24. One day a sample of 64 observations is taken. On another day a sample of 100 observations is taken. Which of the following is true? The standard error of the mean will be smaller with 64 observations. It is impossible to determine any of the above given the available information. The standard error of the mean will be larger with 64 observations. The standard error of the mean will be the same with either 64 or 100 observations.
