A new arthroscopic surgical procedure is found to have a success rate of 297 patients out of 375 trials.

(a) If the traditional surgical procedure had a success rate of 78%, is there evidence to support that claim that the new surgical procedure has a success rate that exceeds the traditional procedure? Use α = 0.05.

(b) What is the p-value associated with the test conducted in part (a)?

Suppose the success rate for surgical treatment of a particular heart condition is widely reported in...
Suppose the success rate for surgical treatment of a particular heart condition is widely reported in the literature to be 0.70. A new medical treatment has been proposed which is alleged to offer equivalent treatment success. A hospital without the necessary surgical facilities or staff has decided to use the new medical treatment on all new patients presenting with this condition. How many patients must be studied to test H0:P=0.70 versus Ha:P=0.70 at the 0.05 level if it is desired...

A study investigating rates of fatalities among patients with serious traumatic injuries found that out of 150 patients transported by helicopter, 19 died. For ground transportation (ambulance) 44 out of 400 died. Use α = 0.01 to test the claim that the rate of fatalities is higher for patients transported by helicopter. Please provide all six steps of the hypothesis test, and use a p-value to make your decision.

A hospital reported that the normal death rate for patients with extensive burns (more than 40% of skin area) has been significantly reduced by the use of new fluid plasma compresses. Before the new treatment, the mortality rate for extensive burn patients was about 60%. Using the new compresses, the hospital found that only 44 of 93 patients with extensive burns died. Use a 1% level of significance to test the claim that the mortality rate has dropped since using...

A food manufacturer claims that eating its new cereal as part of a daily diet lowers total blood cholesterol levels. The table shows the total blood cholesterol levels​ (in milligrams per deciliter of​ blood) of seven patients before eating the cereal and after one year of eating the cereal as part of their diets. Use technology to test the mean difference. Assume the samples are random and​ dependent, and the population is normally distributed. At α=0.05​, can you conclude that...

Question 21 Suppose a health insurance company is interested in carrying out an investigation as to the annual expenditures per household on their healthcare costs. In order to most accurately report their figures, the company decides to ensure “virtual certainty” about their estimates by using a Z value of 3.0 for their calculations. The company conducts a SRS of 843 households and determines the sample average household expenditures on healthcare is $43,257.00. A) Assume the company uses a σ=$879.00. Calculate...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
