Answer:
7/12
Step-by-step explanation:
1, 2, 3, 4, 5, 6, and 7, are all possible rolls less than 8. that's seven combos.
Seven out of twelve. That's 7/12. So the probability of rolling a number less than 8 on a 12 sided die is 7/12.
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.
What do you mean? What’s the question?
Its C. because that is the only one that only one x value
