Question
Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 75.8 beats per minute. Four of the pulse rates are 88, 56, 95, and 66 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 as a. Find the missing value. determined? (The result is referred to as the number of degrees of freedom.) a. The missing value is 74 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.) A. Of the n values, can be freely selected because the remaining value(s) must be equal to the known mean. B. O then values, can be freely selected because the remaining value(s) can be expressed i terms of the assigned values and the knwn men. OC. Of the n values, can be freely selected because the remaining value(s) can be expressed in terms of the mean, median, and midrange of the assigned values Click to select and enter your answer(s) and then click Check Answer Clear All All parts showing a)Explanation / Answer
a)
(75.8*5)-(88+56+95+66)=74
b)
Of the n values, n-1 can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known mean
