$16(4 shirts)= $64
5%=$64(0.05)=$3.20
Jamal's total is $67.20
Considering the situation described, we have that:
a) The critical value is of z = -1.645.
b) Since the test statistic is less than the critical value, we should reject the null hypothesis H0.
<h3>What is the critical value?</h3>
We have a left-tailed test, as we are testing if the proportion is less than a value. Hence the critical value is z with a p-value equals to the significance level, hence z with a p-value of 0.05, hence z = -1.645.
<h3>What is the decision?</h3>
Considering the test statistic, for a left-tailed test, we have that:
- Less than the critical value: Reject H0.
- Equal or greater: Do not reject.
In this problem, z = -2.39 is less than -1.645, hence we should reject the null hypothesis H0.

Answer:
i dont know if this is right but 0.125 for every one cup i got this by dividing the fractions
Answer:
50
Step-by-step explanation:
4 x 10 = 40 and 2 x 5 = 10 so add them together
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
