- Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00 degrees C. A thermometer is randomly selected and tested. Draw a sketch and find the temperature reading corresponding to Upper P 84, the 84 th percentile. This is the temperature reading separating the bottom 84 % from the top 16 %. A. Which graph represents Upper P 84? B. The temperature for Upper P 84 is approximately (Round to two decimal places as needed.)The values listed below are waiting times (in minutes) of customers at two different banks.

The five pulse rates have a mean of 68.6 beats per minute. Four of the pulse rates are 74, 70, 51, and 93. a. Find the missing value. b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of the n values can be freely assigned before the remaining values are determined? (The result i referred to as the number of degrees of freedom.) a. The missing value is beats per minute. (Type an integer or a decimal. Do not round.) b. Select the correct choice below and fill in the answer box to complete your choice. (Type an expression using n as the variable.) OA. Of the n values, OB. Of the n values, O C. Of the n values, (...) can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known mean. can be freely selected because the remaining value(s) can be expressed in terms of the mean,…Answer for b c dSuppose there are 5 students in a room. The mean age is 19.8 years, and the median age is 19. If the youngest person leaves and is not replaced by another person, what happens to the mean and the median? O The mean and median increase. The mean increases, and the median either increases or stays the same. The mean increases, but it is impossible to determine whether the median increases, decreases, or stays the same. The mean increases, and the median stays the same. The median increases, and the mean either increases or stays the same.The geometrlc mean Is under O a. Measures of Location O b. None c.
