Answer:
Mean = 0, Standard deviation = 1
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 77.5 beats per minute
Standard Deviation, σ = 11.6 beats per minute
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
Given:
The matrix multiplication
To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is and the order of second matrix is
, then the order of these two matrices is
.
We have,
Here, the order of first matrix is and the order of the second matrix is
. So, the order of the second matrix is
. It is also written are 2 by 1.
Therefore, the correct option is A.
