Transcribed Image Text:A certain drug is used to treat asthma. In a clinical trial of the drug, 29 of 289 treated subjects
experienced headaches (based on data from the manufacturer). The accompanying calculator
display shows results from a test of the claim that less than 9% of treated subjects experienced
headaches. Use the normal distribution as an approximation to the binomial distribution and
assume a 0.05 significance level to complete parts (a) through (e) below.
a. Is the test two-tailed, left-tailed, or right-tailed?
Right tailed test
Two-tailed test
Left-tailed test
b. What is the test statistic?
Z= 0.61
(Round to two decimal places as needed.)
c. What is the P-value?
P-value=

- Provide an appropriate response. If we fail to reject the null hypothesis when the null hypothesis is false, then we have made a Type B error Type I error Correct decision Type II errorarrow_forwardA scientist has read that the mean birth weight, u, of babies born at full term is 7.5 pounds. The scientist, believing that u is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.9 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below.arrow_forwardResearchers conducted an experiment to test the effects of alcohol. Errors were recorded in a test of visual and motor skills for a treatment group of 23 people who drank ethanol and another group of 23 people given a placebo. The errors for the treatment group have a standard deviation of 2.40, and the errors for the placebo group have a standard deviation of 0.78. Assume that the two populations are normally distributed. Use a 0.05 significance level to test the claim that both groups have the same amount of variation among the errors. Let sample 1 be the sample with the larger sample variance, and let sample 2 be the sample with the smaller sample variance. What are the null and alternative hypotheses? OA. H₂:0² = 0²/2 OB.

- In this case, p-value is greater. So null hypothesis should not be rejected, correct?arrow_forwardWhen asked what it means for the result of a hypothesis test to be practically significant (or practically important), Tatum says this means that the P-value is small and the null hypothesis has been rejected. what is wrong about this? i can't read this handwritingarrow_forwardWhich of these is true regarding hypothesis tests? If the P-value is less than the specified alpha level, the null is accepted If the P-value is less than the specified alpha level, the null is rejected in favor of the alternative If the P-value is greater than the specified alpha level, the alternative is accepted none of these statements is true If the P-value is greater than the specified alpha level, the null is rejected in favor of the alternativearrow_forward
