μ1 – μ2 > 0 is an example of an alternative hypothesis expressed formally. TRUE OR FALSE

μ = 196.6 is an example of a null hypothesis expressed formally. True or false

The statement of the alternative hypothesis Ha: μ1 - μ2 < 0, states:Question 5Select one:a.that population mean 1 is smaller than population mean 2.b.that population mean 2 is smaller than population mean 1.c.that population mean 1 is larger than population mean 2.d.that the two population means are the same.

Given the alternative hypothesis Ha: µ1 ≠ µ2 ≠ µ3 ≠ …….. µk. Which are the correct interpretations?

Decide if each of the following three statements are ture or false Statement 1 p > 0.54 is an example of an alternative hypothesis expressed formally. Statement 2 x̄ = 175.9 is an example of a null hypothesis expressed formally. Statement 3 μ1 – μ2 > 0 is an example of a null hypothesis expressed formally.

A study measuring fitness level in teens randomly sampled 100 female teens and 102 male teens with a higher score indicating more fitness. Researchers suspected that the fitness level for female teens is lower than for male teens, and wanted to check whether the data would supported this hypothesis.If μ1 and μ2 represent the mean fitness level for female teens and male teens respectively, which of the following is an appropriate pair of hypotheses in this case?H0: µ1 − µ2 = 0Ha: µ1 − µ2 < 0H0: µ1 − µ2 < 0Ha: µ1 − µ2 = 0H0: µ1 = µ2Ha: µ1 > µ2H0: µ1 − µ2 = 0Ha: µ1 - µ2 > 0
