Question 894763: This is all one question. The systolic blood pressures of a sample of adults are normally distributed, with a mean pressure of 115 millimeters of mercury and a standard deviation of 3.6 millimeters of mercury. The systolic blood pressures of four adults selected at random are 121 millimeaters of mercury, 113 milimeteres of mercury, 106 millimeters of mercury, and 127 millimeters of mercury. complete parts A - C
The graph is that of a bell curve with A being in the left B being in the middle, C being on the mid-right, and D being on the right.

A) Without converting to Z-scores, match the values with the letters A,B,C,D on the Given Graph of the Standard normal distribution. (Type as whole number)
B) find the Z-score that corresponds to each value and check your answers to part A. (Round to two decimial places)
C) Determine whether any of the values are unusual and classify them as either unuual or very unusual. Select the correct answer below and if necessary, fill in the answer box(es) within your choice.
The unusual value(s) is/are BLANK. The very unusual value is/are BLANK.
The very unusual are BLANK. Unusual values are all very unusual.
The unusual values are BLANK. There are no very unusual values.
There are no unusual values.

A is equal to the smallest systolic blood pressure, B is equal to the second smallest, D is equal to the highest systolic blood pressure, and C is equal to the 2nd highest.
A) A = 106
B = 113
C = 121
D = 127
B) Use the formula (x - 115)/3.6 to get the z score.
= -2.5
= -0.56
= 1.67
= 3.33
C) The unusual value(s) is/are . The very unusual value is/are .
