It is well documented that Americans are getting heavier which increases their blood pressure. Below are the systolic blood pressures of a sample of participants:

pressure
203 150 156 163 126 150 104 184 192 155 181 147 143 172 158 147 211 149 139 146 161 173 190 164 151 123 140 115 182 123 114 160 108 144 206 132

Report the z-scores for the following participants in the data:
a)
Participant 34:

b)
Participant 28:

c)
Participant 33:

d)
Participant 4:

e)
Participant 8:

Answer 1

Solution:-

a) z score for participant 34 is - 2.30.

x = 144

By applying normal distribution:-

z = - 2.30

b) z score for participant 28 is - 8.65.

x = 115

By applying normal distribution:-

z = - 8.65

c) z score for participant 33 is - 10.18

x = 108

By applying normal distribution:-

z = - 10.18

d) z score for participant 4 is 1.86.

x = 163

By applying normal distribution:-

z = 1.86

e) z score for participant 8 is 6.46.

x = 184

By applying normal distribution:-

z = 6.46
