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:
B) 0.85M
Step-by-step explanation:
The new fare schedule is the current fare schedule reduced by 15% of current fares:
... M - 0.15M = 0.85M
Well you gotta find out what x means
