Answer:
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 114.8 mm Hg
Standard Deviation, σ = 13.1 mm Hg
Sample size = 23
We are given that the distribution of systolic blood pressures is a bell shaped distribution that is a normal distribution.
Formula:

Standard error due to sampling:

P(blood pressure is between 119 and 122 mm Hg)

0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Answer:
11
Step-by-step explanation:
Given: 
Using PEDMAS rule to solve it.
Now, simplifying:
We first open parenthesis which is (-7) = -7
= 
Now, we evaluate the exponent which is 
Next, we divide -36 by 12 to get -3
=
Next, we multiply -2 and -7 to get 14
= 
Lastly, we add -3 and 14 to get 11
= 
∴ Answer is 11

Answer: False
Step-by-step explanation: Absolute value means <em>distance from zero</em> on a number line. A common mistake is to assume that absolute value is always positive but that's not necessarily the case.
Take 0 for example.
It's 0 units away from zero on a number line which
means it has an absolute value of zero.
However, all other numbers besides zero will have
an absolute value that is positive.
