Question A physical therapist is interested in studying patients recovering from neck injuries. Let the proportion of neck injury patients who fully recover in less than 6 months be p. If the physical therapist wants to know if the proportion of neck injury patients who fully recover in less than 6 months is more than 75%, what are the null and alternative hypotheses? Select the correct answer below: H0: p=0.75; Ha: p>0.75 H0: p=0.75; Ha: p<0.75 H0: p>0.75; Ha: p=0.75 H0: μ=0.75; Ha: μ>0.75
Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 460 randomly selected adults showed that 58% them would erase all of their personal information online if they could. Find the value of the test statistic. The value of the test statistic is. (Round to two decimal places as needed.)
Test the claim that the mean GPA of night students is smaller than 3.3 at the 0.025 significance level.The test is: a. left-tailed b. two-tailed c. right-tailed Based on a sample of 70 people, the sample mean GPA was 3.28 with a standard deviation of 0.06The p-value is: ________ (to 2 decimals)Based on this we: a. Reject the null hypothesis b. Fail to reject the null hypothesis
Show graph representing this problem Find the standardized test statistic Decide whether to reject or fail to reject the null hypothesis and why. Interpret the decision in the context of the original claim.
Twins In 2009 a national vital statistics report indicatedthat about 3% of all births produced twins. Is the rateof twin births the same among very young mothers?Data from a large city hospital found that only 7 sets oftwins were born to 469 teenage girls. Test an appropriatehypothesis and state your conclusion. Be sure theappropriate assumptions and conditions are satisfiedbefore you proceed.
Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 633 randomly selected adults showed that 0.7% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim. The results significantly so there sufficient evidence to support the claim that most adults would not erase all of their personal information online if they could.
Test the claim that the proportion of people who own dogs is less than 33%. A random sample of 1000 people found that 27.8% owned dogs. Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 1% level of significance. Give an answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Based on the hypotheses, find the following: b. Test Statistic = c. p-value = d. Based on the above we choose to e. The correct summary would be:
Test the claim below about the mean of the differences for a population of paired data at the level of significance a Assume the samples are random and dependent, and the populations are normally distributed.

Life on Other Planets Forty-three percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 120 randomly selected individuals and found 69 believed that there is life on other planets. At α=0.01, is there sufficient evidence to conclude that the percentage differs from 43% ?
