HELP AND JUSTIFY UR THINKINg!!
xenn [34]
This seems tricky, but if B can equal anything except 0, can B be anything on the x plane except 0. Meaning you can pick a number that you would justify. Let's say you picked x=2, it still fits the constraints and will connect with point A. (hoped this helped!)

Suppose that the mean systolic blood pressure for women over age seventy is 134 mmHg (millimeters of mercury), with a standard d
IceJOKER [234]

Answer:

See below for answers (in bold) and explanations

Step-by-step explanation:

<u>Part A</u>

According to the Empirical Rule, 99.7% of the data in a normal distribution are ±3σ standard deviations away from the mean. Hence, approximately 99.7% of women over seventy have blood pressures between 134-3σ = 134-3(7) = 134-21 = 113 mmHg and 134+3σ = 134+3(7) = 134+21 = 155 mmHg.

<u>Part B</u>

As 141-134=134-127=7, this represents ±1σ standard deviations away from the mean of 134 mmHg, which corresponds to 68% of the data by the Empirical Rule. Hence, approximately 68% of women over seventy have blood pressures between 127 mmHg and 141 mmHg
