State the null and alternative hypotheses for the following statements.
1. The mean annual income of mine workers is greater than $50,000.
2. More than one half of all internet users make online purchases.
1)
This is the right tailed test .
The null and alternative hypothesis is
H0 :
= $50000
Ha :
> $50000
2)
This is the right tailed test .
The null and alternative hypothesis is
H0 : p = 0.5
Ha : p > 0.5

For the following conjecture, state the null and alternative hypotheses: "The average pulse rate of male marathon runners is greater than 83 beats per minute." The null hypothesis is Ho: (select) 83. The alternative hypothesis is H1 (select) 83.
For the given conjecture state the null and alternative hypotheses. The average distance a person lives away from a toxic waste site is greater than 36 miles. For the given conjecture state the null and alternative hypotheses. The average farm size in 1970 was less than 27 acres.
Hypothesis Problems For the following hypothesis tests: a. State the null (Ho) and alternative (Hi) hypotheses b. State the type of test (right-tailed, left-tailed, or two-tailed) c.
