Answer:
Step-by-step explanation:
x= 1 over 4y-2
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:
110 = 12
110 + 110 + 110 + 110 = 440
so 110 × 4 = 440
4 × 12 =<em><u> 48 days</u></em>
hope this helps
Answer:
x = 2.667
Step-by-step explanation:
so first you wanna isolate the x by adding 2 to both sides
3x - 2 = 6 ---> 3x = 8
then divide both sides by 3 to get the x alone
x = 8/3 = 2.667
