The mean height of a certain kind of plant is 170 centimeters. Suppose we want to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 170. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.

Suppose the present success rate in the treatment of a particular psychiatric disorder for the relevant population is known to be .73 (73%).

13% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 390 people from the inner city surveyed, 70 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.10? b. The null and alternative hypotheses would be: Ho: Select an answer (please enter a decimal) H1: ? 0 Select an answer O (Please enter a decimal) C. The test statistic (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? O a f. Based on this, we should Select an answer the null hypothesis.
A recent study was conducted on cartwheels and it found that only about 17% of all people can do a cartwheel. Is this percent higher for millionaires? There were 380 millionaires surveyed and 80 could do a cartwheel. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v|Select an answer v (please enter a decimal) H1: ? v Select an answer v (Please enter a decimal) c. The test statistic ? v (please round your answer to 3 decimal places.) d. The p-value = (Please round your answer to 3 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the populaton proportion is significantly higher than 17% at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can do a cartwheel is higher than 17%.

A researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the null hypothesis (Ho) put forth about the treatment? O The treatment has an effect on anxiety. O The treatment divides each anxiety score by a constant. O The treatment multiplies each anxiety score by a constant. The treatment has no effect on anxiety.
