Stomach pH values fluctuate between 1.5 and 3.5. The researchers expect that in healthy patients in their study, this will also be the case, and that approximately 50% of the healthy patients will have a stomach pH below 2.5. After collecting data, they find that 30 of 87 healthy patients, or 34.48%, have stomach pH levels below 2.5. Use this information to answer 1.
- Assume that the probability that a healthy patient has a stomach pH below 2.5 is 50%. This will be our null hypothesis. Use the binomial distribution to calculate the probability that 30 or fewer healthy patients from a randomly selected sample of 87 healthy patients will have a stomach pH below 2.5. Show all work.
Homework Answers
Ans:
Use binomial distribution with n=87 and p=0.5
P(30 or fewer)=binomcdf(87,0.5,30)=0.0025

1.) Accrotime is a manufacturer of quartz crystal watches.
Accrotime researchers have shown that the watches have an average
life of 30 months before certain electronic components deteriorate,
causing the watch to become unreliable. The standard deviation of
watch lifetimes is 10 months, and the distribution of lifetimes is
normal.
(a) If Accrotime guarantees a full refund on any defective watch
for 2 years after purchase, what percentage of total production
will the company expect to replace?
(b) If Accrotime...

30. A radioactive waste spill occurred in one area of a town. Researchers want to examine whether the spills inked to increased cancer rates. For several months afterwards, they record the number of people diagnosed with cancer at one hospital near the radioactive spill, and different hospitals across town that are not near the spill. What are the two populations of interest? (2 pts) In this case, what is the null...

The problem and the data: A pharmaceutical company has developed a new drug designed to reduce a smoker's reliance on tobacco. Since certain dosages of the drug may reduce one's pulse rate to dangerously low levels, the product-testing division of the pharmaceutical company wants to model the relationship between decrease in pulse rate, y (beats per minute), and dosage, (cubic centermeters). Different dosages of the drug were...
