Question

You cross-breed a pea plant with unknown genotype (RR or RW) and a pea plant with genotype WW.
Your null hypothesis is that the unknown genotype is RW.
You get 7 offspring, all 7 of them with phenotype R (so their genotype is RW). \\
Can you reject the null hypothesis at the 1% significance level? Use the BPF -- this is in the binomial tables, but also easy on a calculator.

a. the p-value is just 0.78%, so yes.

b. None of the other answers are correct.

c. the p-value is only 0.78%, so no.

d. the p-value is only 4.3%, so the results are inconclusive.

Six researchers at different universities agree to carry out exactly the same social psychology experiment involving three treatment conditions. When the studies are complete, they pool their data to study outcome variable Y, and they carry out a two-way ANOVA. Assuming that 10 subjects were randomly assigned to each of the treatments at each of the sites, what are the degrees of freedom associated with each of the variance components outlined in the ANOVA Table shown below? Two versions of the analysis are planned. In the first analysis, the researchers restrict their interest to the six specific sites included in the joint research. In the second analysis they consider the six universities to be a sample from the population of American universities. For each analysis, look up the critical F values for a =.05, and enter them into the table below. (The critical value is the number the F statistic must exceed to be considered statistically significant at the .05 level.) Also…
4. In one of Mendel’s early genetics experiments, he observed two traits on each of 556 garden peas: shape (Round or Angular) and Colour (Yellow or Green). The results are listed in dataset “Mendel”. According to his model, the four classes should occur in a 9:3:3:1 ratio. Do the data support that presumption? Do a relevant hypothesis test at the alpha of 0.05 level of significance. 4.1.

4) We are running a hypothesis test to see if weight of African zebras is significantly different than that of Arabian horses. We assume weight in both populations is normally distributed and both populations have the same population variance in weight which is unknown to us, so we use the sample variances to estimate the standard error for our calculations. Our sampling has 8 African zebras and 6 Arabian horses. We find 3.01 as the absolute value of our standardized test statistic for our sample data. Is this data significant at the .02 level of significance? NONE OF THE OTHERS NO YES
An article in the newspaper claims that 60% of registered drivers have the organ donor designation on their driver's license. A researcher at a hospital decides to investigate this claim. The researcher selects a random sample of 50 registered drivers and finds that 44.0% have the organ donor designation on their driver's license. Do the data provide convincing evidence at the ?α = 0.05 level that fewer than 60% of registered drivers have the organ donor designation on their license?
The aim of a study is to test the ratio of variances in the weight of two groups of rats being under a certain drugs A ( group 1) and B ( group 2).

To investigate the effect of four treatments on change in body fat mass each of 74 male subjects who were over age 65 was assigned at random to one of the following four treatments: (1) placebo "growth hormone" and placebo "steroid" (denoted by P + P), (2) placebo "growth hormone" and the steroid testosterone (denoted by P + S), (3) growth hormone and placebo "steroid" (denoted by G + P), and (4) growth hormone and the steroid testosterone (denoted by G + S). The accompanying table lists data on change in body fat mass over the 26-week period following the treatment. Carry out an F test to see whether true mean change in body fat mass differs for the four treatments if N = 74, grand total 7 = -158.3, and x = = -2.1392. (Use a significance level of 0.05.)
