Suppose that resting pulse rates for healthy adults are found to follow a Normal distribution, with a mean of 69 beats per minut
pickupchik [31]

Answer:

Approximately 16% of adults have a pulse rate higher than bonnie'.

Step-by-step explanation:

A normal random variable with mean Mu = 69 and standard deviation sd = 9.5 is standardized with the transformation:

Z = (X - Mu) / sd = (X - 69) / 9.5

For a pulse rate value of 78.5, Z = (78.5 - 69) / 9.5 = 1.0

P (X <78.5) = P (Z <1.0) = 0.8413.

P (X> 78.5) = P (Z> 1.0) = 0.1587.

The standard score for the Bonnie's  pulse rate is 1.0.

Bonnie's  pulse rate is at the 1.0 standard deviations above the mean.

Approximately 16% of adults have a pulse rate higher than bonnie'.
