The proportion is 0.4401.
We find z-scores that correspond with both ends of this interval. Z-scores are given using the formula:
For the lower end,
The proportion of scores to the left of this number is 0.2514.
For the higher end, the z-score is
The proportion of scores to the left of this number is 0.6915.
To find just the proportion of scores between these two, we subtract;
0.6915-0.2514 = 0.4401.

Answer:
The inequality equation is ,
Step-by-step explanation:
Let the number of hours she work in Babysitting be b.
Also Number of hours she work in tutoring be t.
She can work at most 8 hours altogether between both jobs in a given week.
We need to find the Inequality expression that would represent the possible values for the number of hours babysitting, b and the number of hours tutoring, t.
It can be framed as;
number of hours she work in Babysitting plus Number of hours she work in tutoring should be less than or equal to 8.
Expressing in mathematical form we get;
Hence the Inequality is given as .
