Increasing alpha will:a) Decrease study powerb) Increase study precisionc) Increase the probability of a Type II errord) Increase the probability of a Type I errore) All of the above

The study cited in Exercise 5.3.1 reported an estimated mean serum cholesterol level of 183 for women aged 20–29 years. The estimated standard deviation was approximately 37. Use these estimates as the mean m and standard deviation s for the U.S. population. If a simple random sample of size 60 is drawn from this population, find the probability that the sample mean serum cholesterol level will be: (a) Between 170 and 195 (b) Below 175 (c) Greater than 190
Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 14. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 14. The value of the mean is μ = 10.5 peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is o = (Round to one decimal place as needed.) Values of (Round to one decimal place as needed.) ... b.

Which of the following statements are true? There may be more than one true statement; check all that are true. Question 11 options: a) The only reason to carry out an observational study instead of an experiment is if we do not have enough money to run the experiment. b) The variance of the sample mean depends on the sample size and the population variance. c) For large sample sizes, the sample mean will tend to have a normal distribution, whereas for small sample sizes it will tend to have a uniform distribution. d) Randomization can be a useful tool in statistical studies, but only for large sample sizes.
Suppose that all the students registered to the probability and statistics course have to buy textbook. The 28 % of all students demand a new book, on the other hand the other 72 % want a used text book. Consider randomly selecting 40 purchasers.a. What are the mean value and standard deviation of the number who want a new copy of thebook?b. What is the probability that the number who want brand-new books is more than 1.5σ awayfrom the mean value?c. The bookstore has 30 new and 30 used textbooks in stock. If 40 people come in one by one topurchase this text, what is the probability that all 40 will get the type of book they want fromcurrent stock? [Hint: Let X = the number who want a new copy. For what values of X will all 40get what they want?]
