We are given that the distribution of pulse rates of women is a bell shaped distribution that is a normal distribution.
Formula:
Putting the values, we get,
After, the standardization, that is conversion of all pulse rates of women to z scores, the mean of the distribution is 0 and standard deviation is 1.
Mean = 0, Standard deviation = 1
let's bear in mind that sin(θ) in this case is positive, that happens only in the I and II Quadrants, where the cosine/adjacent are positive and negative respectively.
