Several questions are based on the following information. A strong relationship between ocean temperature and the probability of tropical storms in the Caribbean has been established. The variable T represents water temperature in degree Fahrenheit and Pis the probability of a tropical storm. It has been verified that when water temperature is 80F, the probability of a tropical storm is .04. When water temperature is 82F, the probability of a tropical storm is .08. Assume the relationship between P and T is linear. An increase in T of 1 degree would increase P by approximately a. 0.01 b. 0.02 c. 0.03 d. 0.04.

Q.1 Dr. Star is interested in whether the physical coordination skills among low-income pre-school children are different from those of other children. She knows the population mean for the Pre- School Coordination Activity Test (PCAT) is 120 with o x= 10. She tests 80 preschoolers from low-income families and obtains an X= 122. a. Should Dr. Star do a one-tailed or a two-tailed test? Explain your answer. b. State the appropriate H o and H a , given your answer in part a. c. Use at a = 0.05. What is the value of zcrit ? d. Calculate z obt e. Using symbols, report your findings. f. What should Dr. Star conclude?

A test was given to a statistics class. Results for each gender and for one student in each gender are given. From the information provided, determine which student received a relatively higher grade. The female scored a 78 with μ=84 and σ=3. The male scored a 80 with μ=86 and σ=2. The female student has a higher relative grade than the male student The male student has a higher relative grade than the female student Both students have the same relative grade Not enough information to determine
