- If the alleles A and B of the cystic fibrosis gene occur in a population with frequencies p and 1 - p (where pis between 0 and 1), then the frequency of heterozygous carriers (carriers with both alleles) is 2p(l - p). Which value of p gives the largest frequency of heterozygous carriers?A research center claims that more than 25 % of employees in a certain country have changed jobs in the past four years. In a random sample of 260 people from that country, 78 have changed jobs in the past four years. At alpha equals0.05 , is there enough evidence to support the center's claim? Complete parts (a) through (e) below. (a) Identify the claim and state Upper H 0 and Upper H Subscript a . Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. At most nothing % of employees in the country have changed jobs in the past four years. B. More than nothing % of employees in the country have changed jobs in the past four years.

Averages of three succesive bags were plotted, and 47.5% of these were observed to lie between 51 and X pounds. Estimate the value of X. State assumptions you make and say whether these assumptions are likely to be true for this example.
- Gaydar Exercise 10 in Chapter 1 describes a study thatshowed that heterosexual women, during ovulation, weresignificantly better at correctly identifying the sexualorientation of a man from a photograph of his face than women who were not ovulating. In other words, ovula-tion improves a woman’s “gaydar.” Near ovulation, on average women correctly identified the orientation ofabout 65% of the 100 men shown to them. If this is theprobability of correctly identifying the orientation of aman in any given photograph, what is the probability awoman would correctly classify 80 or more of the men(as two women in the study did)?Is there a significant difference on the ratings of the respondents on X15 when grouped according to X2? Statement of the Problem: Is there a significant difference on New Product – X15 when grouped according to Industry Type – X2? Null Hypothesis: There is no significant difference on New Product – X15 when grouped according to Industry Type – X2. Note: The coding for Industry Type is 0 for Magazine Industry and 1 for Newsprint Industry. Interpret the T-Test ResultType II error occurs when an individual fails to reject H0 when H0is false

- A researcher wants to find the effect of a special diet on systolic blood pressure. A sample of 7 adults was selected to start them on this diet for 3 months. Based on this information, can it be stated that systolic blood pressure changes with the special diet? Based on the findings of the test carried out, it is possible to conclude that...... A. systolic blood pressure does not change with special diet B. systolic blood pressure changes with special diet C. systolic blood pressure is lower with the special diet D. systolic blood pressure is higher with the special diet E. It is not possible to conclude anything regarding systolic blood pressure with the special dietQ: Provide the null and alternative hypotheses for this analysis.

So, within a field, he randomly assigned each variety to five plots. The yield[s] in pounds per acre were recorded for each plot. Go back to the original experiment in (1) where we are only interested in variety, not fertilizer. The agronomist realized that he wanted his results to apply over a range of soil conditions. So, he decided to conduct the experiment on 4 different locations (subdivisions) in a field so that the elevation and type of soil vary. He planted each variety on one plot within each subdivision of the field. Again, the yield[s] in pounds per acre were recorded for each plot. (d) What are the experimental units in the study? How many are there in total? (e) What is the name of the design of this experiment? (Single factor, two-factor, block) (f) Outline the design of the experiment.
