In a clinical trial of the drug, 18 of 289 treated subjects experiencedheadaches (based on data from the manufacturer). The accompanying calculator display shows results froma test of the claim that less than 11% of treated subjects experienced headaches.

The display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 5.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Click the icon to view the display from technology. ..... Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? Ο Α. Η : μ 5.00 Mbps D. Ho: µ= 5.00 Mbps H1: µ#5.00 Mbps Identify the test statistic.

For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.037. If the test is being conducted at 99% confidence, the null hypothesis could be rejected or not rejected depending on the sample size could be rejected or not rejected depending on the value of the mean of the sample is not rejected is rejected

1) If your p-value is less than a significance level , then your decision is to fail to reject the null hypothesis. True or False 2)The test statistic, z, in a hypothesis test measures the difference between the sample proportion and the hypothesized proportion in terms of standard deviations. True or False
How would a person set up the hypotheses if they wanted to test the claim: the mean length of a Pyramid Lake trout is greater than 21 inches? What would be a type Il error in this case? O State the mean length of a Pyramid Lake trout is greater than or equal to 21 inches when in fact the mean length of a Pyramid Lake trout is less than 21 inches.

The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 75% of all fatally injured automobile drivers were intoxicated. A random sample of 52 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 75% in Kit Carson County? Use ? = 0.10. (a) What is the level of significance? State the null hypothesis H0 and the alternate hypothesis H1 . H0 : p H1 : p (b) What sampling distribution will you use?
