Chapter 12.1, Problem 13E
A certain genetic characteristic of a particular plant can appear in one of three forms (phenotypes).
A researcher has developed a theory, according to which the hypothesized proportions are p1 = 0.25, p2 = 0.50, and p3 = 0.25. A random sample of 200 plants yields X2 = 4.63.
- a. Carry out a test of the null hypothesis that the theory is correct, using level of significance α = 0.05.
- b. Suppose that a random sample of 300 plants had resulted in the same value of X2. How would the analysis and conclusion differ from those in Part (a)?

Production records indicate that in normal operation for a certain electronic component, 93% have no faults, 5% have one fault, and 2% have more than one fault. For a random sample of 500 of these components from a week’s output, 458 were found to have no faults; 30, to have one fault; and 12, to have more than one fault. Test, at the 5% level, the null hypothesis that the quality of the output from this week conforms to the usual pattern.
The manufacturer of a spot remover claims that hisproduct removes 90 percent of all spots. If, in a random
sample, only 174 of 200 spots were removed with the man-ufacturer’s product, test the null hypothesis θ = 0.90
against the alternative hypothesis θ < 0.90 at the 0.05level of significance.
Historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous six months, in a sample of 115 new car buyers, 46 have traded in their old car. To determine (at the 10% level of significance) whether the proportion of new car buyers that trade in their old car has this is  statistically significantly decreased, what can you conclude concerning the null hypothesis?
A) reject the null hypothesis
Or
B) fail to reject the null hypothesis

- 31% of all pygmy softshell tortoises have stripes on their shells. A herpetologist in Cititon collects a sample of 28 pygmy softshell tortoises and finds that 8 of them have stripes on their shells. Is there enough evidence to conclude, at a significance of alpha = 0.05, that the proportion of pygmy softshell tortoises in Cititon with stripes on their shells is less than 31%? What is the claim? What is the null hypothesis? What is the alternative hypothesis? What is the test statistic? What is/are the critical value(s)? Do we reject the null hypothesis? What conclusion do we draw? What is the P-value for the problem above?arrow_forwardSuppose you surveyed a sample of 100 in-state students at public colleges in Pennsylvania and a sample of 100 in-state students at public colleges in Ohio and found that the average difference in tuition between the two groups is $2,982, 95%CIs[$1,769, $4,195]. Based on this confidence interval, would you reject the null hypothesis or fail to reject the null hypothesis if you had conducted a two-tailed hypothesis test with alpha = .05 to see if there is a significant difference between the two groups?

At six months of follow-up, 141 subjects in the intervention group reported having had sex (with men and/or women) since randomization. Of these 141 men, 114 had been tested for HIV since being randomized. At six months of follow-up, 147 subjects in the control group reported having had sex (with men…arrow_forward
