Step-by-step explanation:
We know that Frank has 2 gardens, one with <em>y</em> vegetable seeds and another with 3<em>y</em> + 8 vegetable seeds. If we are trying to find the <em>total</em> amount of seeds planted, we must add the 2 gardens together:
Garden 1: <em>y</em>
Garden 2: 3<em>y</em> + 8
Garden 1 + Garden 2 = Total veggie seeds
<em>y</em> + 3<em>y</em> + 8 = Total veggie seeds
Total veggie seeds = 4y + 8

Answer:
Step-by-step explanation:
Given that :
Mean = 7.8
Standard deviation = 0.5
sample size = 30
Sample mean = 7.3 5.4772
The null and the alternative hypothesis is as follows;


The test statistics can be computed as :




The p-value at 0.05 significance level is:
p-value = 1- P( Z < -5.4772)
p value = 0.00001
Decision Rule:
The decision rule is to reject the null hypothesis if p value is less than 0.05
Conclusion:
At the 0.05 significance level, there is sufficient information to reject the null hypothesis. Therefore ,we conclude that college students watch fewer movies a month than high school students.
