A certain adjustment to a machine will change the length of the parts t makes but will not affect the standard deviation. The length of the parts s narmally distributed, and the standard deviation is0.5 mm. After on adjustment is mate, a rendom sampie is taken to determine the mean length of parts now being produced. The retulting lengths ant as folows75,6 76.1 75.1 77,1 75.5 76.0 76.8 75.0 76.6.77.9(a) What is the parameter of interestmean lengthsample sizeOchange in mean since adjustmentOstandard deviation of length(0) Find the point estimate for the mean length of all sarts now being produced.

The Ahmadi Corporation wants to increase the productivity of its line workers. Four different programs have been suggested to help increase productivity. Twenty employees, making up a sample, have been randomly assigned to one of the four programs and their output for a day's work has been recorded. You are given the results below. At 95% confidence, conduct the ANOVA test to determine whether there is a significant difference in the mean output under the four programs.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Years in which U.S. presidents were inaugurated Choose the correct answer below. O A. The nominal level of measurement is most appropriate because the data cannot be ordered. OB. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point. OC. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. OD. The interval level of measurement is most appropriate because the data can be ordered, differences can be found and are meaningful, and there is no natural starting zero point. DELL Nex

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. A thermometer is randomly selected and tested. Draw a sketch and find the temperature reading corresponding to P34, the 84th percentile. This is the temperature reading separating the bottom 84% from the top 16%.

Ay X The temperature for P84 is approximately (Round to two decimal places as needed.)
At their inauguration, the ages of the first six (out of a current number of 45) presidents of a certain country were 60, 51, 50, 58, 51, and 55 . Complete parts a and b below. a. Find the mean age at inauguration of the first six presidents. The mean is 54.254.2. (Round to the nearest tenth as needed.) The mean of the most recent six presidents was 51.6. Did the first six presidents tend to be a bit older or a bit younger than the most recent six presidents? older Your answer is correct. younger b. Find the standard deviation of the ages at inauguration of the first six presidents. The standard deviation is nothing. (Round to the nearest tenth as needed.)
