valkas [14]

Answer:

c) t-test of population mean

Explanation:

The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.

Example we compare our test variable to the hypothesized mean value $75 above.

The t test is used instead of z score when standard deviation is unknown.

Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.

zepelin [54]
First make it that both denominators are the same.
(\frac{1}{2}  \times 5) + ( \frac{2}{5} \times 2) =  \frac{5}{10}  +  \frac{4}{10}
Then add both numerators
\frac{5}{10}  +  \frac{4}{10}  =  \frac{9}{10}
Your final answer should be
