I already have my answers, I just want to double-check so that I can perfect this. Thank you!

Formulating Appropriate Null and Alternative Hypotheses on a Population Mean Directions: Choose the best answer to the given questions or statements. 1. This hypothesis states that there is no difference between population parameters and the hypothesized value. A. hypothesis C. alternative hypothesis B. null hypothesis D. two-tailed hypothesis 2. When the value of parameter has significant difference with the hypothesized value, then it is called A. one-tailed test C. null hypothesis B. two-tailed test D. alternative hypothesis 3. The sign of the alternative hypothesis in a left-tailed test is always A. equal B. less than C. not equal D. greater than 4. If the researcher wishes to test the claim that the mean of the population is 75, the appropriate null hypothesis is: A. A $ 75 B. # 2 75 C. A $ 75 D. A = 75 5. A researcher thinks that if expectant mothers use vitamins, the birth weight of the babies will increase. The average birth weight of the population is 3.9 kgs. What is the alternative hypothesis? A. Ha: H > 3.9 B. Ha: u 2.8 B. Hail 15 D. H 500 11. On average, the household electricity consumption in the country was about 248.1-kilowatt hours in 2015. Electricity was used primarily for lighting purposes, cooking, recreation, and space cooling. Which inequality symbols are correct (=, #, 2, ) for the null and alternative hypotheses: Ho: / _ 248.1 Ha: / _ 248.1? A. =,> B. C. =,# D. S.Z 12. Which is the correct alternative hypothesis for one-tailed test? A. H = 25 B. H # 25 C. H 2 25 D. H P116, 714.00 D. Ho: H = P116, 714.00, Ha: H
