Answer:
D.) If the mean typing speed of workers from the agency is 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.
Step-by-step explanation:
In this case, the p value is what let's us determine the probability of getting the desired outcome. This would be 60 wpm.
If it is lower than the desired outcome, we know that this inference is not the <em>actual mean </em>of the data.
Answer:

Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example

and

ARE Conjugates.
The conjugate of

is

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be

We can apply the difference of squares for the denominator.

So our denominator will be

So our rationalized fraction will be

Use Photomath for this it’s much easier
