Answer:
The number of people on each bus is 32
Step-by-step explanation:
We are given
Total number of students =267
Total number of adults =21
So,
Total number of passengers = ( Total number of students)+(Total number of adults)
now, we can plug values
Total number of passengers =267+21
Total number of passengers =288
We are given
Number of buses=9
so,
Number of passengers on each bus = (total number of passengers)/( Number of buses)
now, we can plug values
Number of passengers on each bus is
So,
The number of people on each bus is 32

<h2>
Answer with explanation:</h2>
Let p represents the population proportion.
By considering the given information, we have
∵ the alternative hypothesis is two tailed , so the test is two-tailed test.
Given : For sample size :n= 130, 
Test statistic: 
P-value (two -tailed test)=
Since , the p-value (0.131) is greater than the significance level (0.03), so we accept the null hypothesis.
Thus , we conclude that we have sufficient evidence to support the null hypothesis that the true population proportion of Maryland students who have smoked marijuana is 29% .
