You are thinking of employing a t procedure to test hypotheses about the mean of a population using a significance level of 0.05

. You suspect the distribution of the population is not Normal and may be moderately skewed. Which of the following statements is correct?
a. You should not use the t procedure because the population does not have a Normal distribution.
b. You may use the t procedure, but you should probably claim the significance level is only 0.10.
c. You may use the t procedure, provided your sample size is large, say, at least 40.
d. You may not use the t procedure because t procedures are robust to non-Normality for confidence intervals but not for tests of hypotheses.

Answer:

b. You may use the t procedure, but you should probably claim the significance level is only 0.10.

Step-by-step explanation:

A t-test is generally used to compare the mean of two groups when the data comes from a normal distribution. If the distribution is not normal we can still perform a t-test but the sample size should be large enough.

Please help me with this math problem!!
xz_007 [3.2K]

Answer:

y=3

Step-by-step explanation:

This is an isosceles triangle because the two angles at the bottom are equal.

This means the two sides are equal

5y-2 = 13

Add 2 to each side

5y-2+2 =13+2

5y = 15

Divide each side by 5

5y/5 = 15/5

y =3
