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.
B
Because 2 sqrt5 is = to sqrt 20.
4^2=16, 6^2=36
15$, I just multiplied 25 by .4 the product is 10 then just subtract that
