Answer:
0.0214
Step-by-step explanation:
We can get these answer by finding the z-scores at first
Mathematically;
z-score = x-mean/sd
For 900;
z-score = 900-750/75 = 150/75 = 2
For 975
z-score = (975-750)/75 = 3
So the probability we want to calculate is;
P(2<x<3)
This can be calculated using the standard normal distribution table
From the standard score table;
P(2<x<3) = 0.0214
782,444 rounded to the nearest hundred thousand would be 800,000.
This is because we know that the hundred thousands place has a 7 in it, so it would be 700,000. However, because 8 is greater than 5, we have to round up instead of down.
Hope this helps!
