Using the p-value method, the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.
<h3>What is the relation between the p-value and the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, we have a two-tailed test, as we are testing if the mean is different of a value. For a significance level of 0.1, the critical value of z(when a p-value of 0.1 is obtained) is of |z| = 1.645, hence the decision rule is:
- |z| < 1.645: do not reject the null hypothesis.
- |z| > 1.645: reject the null hypothesis.

The discount percent is 20% off because you would subtract the discount from the original price and get 45. 45 is 20% of 225.

Answer:
whatever 31-18 is i think
Step-by-step explanation:
Answer:
the answer is <u>yes</u> it does show a <u>proportional relationship.</u>
Step-by-step explanation:
Lets put it in a table:
<u>T</u> <u>C</u>
1 .5
2 1
3 1.5
4 2
5 2.5
if we were to keep going to <u>20 tickets</u>, then we would reach <u>$10</u>.<u> Each tickets price will increase by 50¢. </u>
(Hope this helps!)
