Answer:
0.1019
Step-by-step explanation:
Probability, p=12%=0.12
Sample size, n=130 students
Those writing with left=14 students
Using the formula for binomial distribution
P(X≤x)=
Substituting 0.12 for p, 130 for n, 14 for x we obtain
P(X≤x)=
P(X≤x)=
P(X≤x)=0.1019
Answer:
The percent change in salary from one job to the next is 88.57%.
Step-by-step explanation:
The previous salary of per hour = $8.75 per hour
The current salary of per hour = $16.50 per hour

=$7.75 per hour
⇒The change in the salary per hour rate is $7.75
Now,
=
or, the change in salary percentage is 88.57%
Hence, the percent change in salary from one job to the next is 88.57%.
