Question 15 of 20 (1 point) view problem in a pop-up assume that the mean systolie blood pressure of normal adults is 120 millimeters of mercury (mm hg) and the standard deviation is 5.6. assume the variable is normally distributed. use a graphing calculator and round the answers to four decimal places. part 1 if an individual is selected, find the probability that the individual's pressure will be between 120.4 and 121.9 mm hg. p120a

0.1052

Step-by-step explanation:

Given : Mean :

Standard deviation :

We assume the variable is normally distributed.

The formula for z-score is given by :-

For x=120.4

For x=121.9

The p-value =

The probability that the individual's pressure will be between 120.4 and 121.9 mm Hg = 0.1052

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
