Answer:
try b=32
Step-by-step explanation:
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:the answer is
Step-by-step explanation:
First convert 7 1/2 to an improper fraction
15/2 ÷ 3/4
Division of fractions hold the first fraction replaces ÷ with x then flip the second fraction
15/2 x 4/3
Multiply the tops 15x4 =60
Over the bottoms multiplied together 2x3=6
60/6=10

Answer:
219.15% (2DP)
Step-by-step explanation:
The difference between 0.94 and 3 is 2.06
Percentage change = (change in value/ original amount) X100.
(2.06/0.94) X 100
Which equals 219.15%
