Answer:
At least 37.74% of the procedures takes between 97.6 and 125.6 minutes
Step-by-step explanation:
The percentage is the area of the standard normal distribution curve between the values 97.6 and 125.6
The standard normal variate of the given data is found as

Thus for the given values Z is calculated as under

Similarly for the other value we have

Thus the area between the calculated values can be found from standard normal distribution table to be 37.74%
Answer:
Hence, option: A is the correct answer.
A. As the x-values increase, the y-values tend to increase.
Step-by-step explanation:
It is given that:
A scatterplot has a positive, linear correlation.
By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.
Hence, the statement which is true about the relationship between the x- and y-values is:
A. As the x-values increase, the y-values tend to increase.
