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.

There are two functions that can be used to describe the percent of people 25 years and older who have completed at least high s
Korvikt [17]

Answer:

g(15)=93.8\%

see the explanation

Step-by-step explanation:

Let

x ----> the number of years since 2008,

g(x) ----> the percent of people 25 years and older who have completed at least high school

we know that

g(x)=0.008x^2+0.42x+87.5

so

For x=15 years since 2008

substitute

g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%

That means

In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%

20% of the shoes in a factor are black. One shoe is chosen and replaced. A second shoe is chosen and replaced. Then a third shoe
Dafna1 [17]
The probability that none of the shoes are black is 51.2%.

If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.

0.8 x 0.8 x 0.8 = 0.512 = 51.2%
