What am I supposed to be solving for?
Answer:
Surface Area = 6.28 x 5.223 x 3 + 6.28 x 10.446 = 164 cm^2
Step-by-step explanation:
A=2πrh+2πr2
When we divide 245 by 1.5 we find 164cm^2
Answer:
D. 126
Step-by-step explanation:
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.
