September=$560
October=$210
November= $280
Step-by-step explanation:
Total amount left to save $1400.
We calculate the amount save each mount since we are already given the percentages.
For the month of August she saves 25% of $1400, we convert the percentage to equivalent cash
for the month of August, she saved $350,
Next For the month of September she saves 40% of $1400, we convert the percentage to equivalent cash
for the month of September, she saved $560,
Next For the month of October she saves 15% of $1400, we convert the percentage to equivalent cash
for the month of October, she saved $210,
total amount saved by October = $350+$560+$210=$1120
Amount saved by November=1400-1120=$280
<h2><u>Answer with explanation:</u></h2>
Let p be the proportion of voters in a certain state support an increase in the minimum wage.

Since alternative hypothesis is right-tailed so the test is a right-tailed test.
Test statistic :
, where n= sample size.
p= population proportion.
= sample proportion.
. In a random sample of 300 fast food workers for 240 supporters increase an minimum-wage.
i.e. n= 300 and
Then,
For significant level α = .05 , the critical z-value is
Decision : Since calculated z-value (3.78) is greater than the critical value (1.645) , so we reject the null hypothesis.
Conclusion : We have sufficient evidence o support researcher's claim that that the percentage of fast food workers for support and increase is higher than 70%..
