Answer:
We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case would be:
Ha: p > 0.15
Step-by-step explanation:
Information given
n=250 represent the random sample taken
X=40 represent the number of people on the alumni mailing list
estimated proportion of people on the alumni mailing list
is the value to verify
z would represent the statistic
represent the p value

1 hour and 30 minutes
5.50 x 3 is 16.50 plus the additional 2 dollar tip
1/4 + 3/10
find the common denominator which is 20
multiply by 5 for 1/4
1(5)/4(5)=5/20
multiply by 2 for 3/10
3(2)/10(2)=6/20
5/20+6/20=11/20
answer:
11/20
