According to the CDC (2016), the average life expectancy of someone with diabetes is µ = 72 years, standard deviation= 14. Suppose that a sample of    n=64 people diagnosed with diabetes who received a blood glucose monitoring implant had an average life expectancy of M = 76 years. Test the hypothesis that the glucose monitoring implant changes life expectancy. Assume a two-tailed test, alpha: = .05.

The mean life expectancy in the US pop. is currently 81.1 years with a standard deviation of 15.9. A researcher examined the age of death of 70 people in Florida hospitals and the mean was 85.2 yrs. He runs a 2tailed test with a=.05 to see if FL has significantly different life expectancy to the overall US pop. Calculate the standard error, z statistic and critical z values from this information.

It takes an average of 14.5 minutes for blood to begin clotting after an injury.  An EMT wants to see if the average will increase if the patient is immediately told the truth about the injury. The EMT randomly selected 65 injured patients to immediately tell the truth about the injury and noticed that they averaged 15.4 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.05 minutes. What can be concluded at the the αα = 0.05 level of significance? For this study, we should use     The null and alternative hypotheses would be:       H0:H0:                   H1:H1:               The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is     αα Based on this, we should      the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly greater than 14.5 at αα = 0.05, so there is statistically significant…

It takes an average of 10.8 minutes for blood to begin clotting after an injury.  An EMT wants to see if the average will increase if the patient is immediately told the truth about the injury. The EMT randomly selected 46 injured patients to immediately tell the truth about the injury and noticed that they averaged 11.7 minutes for their blood to begin clotting after their injury. Their standard deviation was 2.98 minutes. What can be concluded at the the αα = 0.05 level of significance?

What raw score for age corresponds to a z- score of +4.50, given a mean of 12.0 years and a standard deviation of 4.0 years?

A trial study suggest that the standard deviation for the half life for the drug chlordiazepoxide is 8 hours. With 99% confidence, find the sample size needed to determine the mean half life for the drug with a margin of error of 3 hours.

The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 253.8 and a standard deviation of 61.7. What is the approximate percentage of women with platelet counts between 192.1 and 315.5?

It takes an average of 12.7 minutes for blood to begin clotting after an injury.  An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 51 injured patients to immediately tell the truth about the injury and noticed that they averaged 12.4 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.77 minutes. What can be concluded at the the αα = 0.10 level of significance?
