A dental assistant is interested in the proportion of patients that need a root canal. Let the proportion of patients that need a root canal be p. If the dental assistant wanted to know if the proportion of patients that need a root canal is more than 20%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.20; Ha: p<0.20 H0: p>0.20; Ha: p=0.20 H0: p=0.20; Ha: p>0.20 H0: μ=0.20; Ha: μ>0.20

Suppose the present success rate in the treatment of a particular psychiatric disorder for the relevant population is known to be .73 (73%). A research group hopes to demonstrate that the success rate of a new treatment will be better than this standard. Use the letter p to represent the success rate of the new treatment.

Recall the scenario from the previous page. A psychic claims to be able to predict the outcome of coin flips before they happen. Someone who guesses randomly will predict about half of coin flips correctly. In 100 flips, the psychic correctly predicts 57 flips. Do the results of this test indicate that the psychic does better than random guessing? The hypotheses are H0: p=0.50p=0.50 Ha: p>0.50p>0.50 where p is the proportion of correct coin flip predictions by the psychic. 1. determine the P-value. 2. Give the conclusion based on the P-value above. Use a 5% level of significance.
Automobile accident and asked what they saw. One group of students was asked how fast were they going when they smashed into the car? Other group verb was changed to hit. Smashed into reported higher rates of speed than hit. Suppose a researcher repeats this study with current college students and obtains the following results. Smashed into Hit n=15 n=15 M=40.8 M=34.0 SS=510 SS=414 1. State the hypothesis 2. Do the results indicate a significantly higher estimated speed for the smashed into group? Use a two-tailed test with a=.05. Compute estimated Cohen's D to measure size of the effect. State numerical value and meaning.
