Below is a section of a corncob. This represents the colors and shapes of the grains produced in the dihybrid F2 results of a cross. [the number of grains is not representative] The characters are ‘grain shape’ and ‘grain color.’ Round shape is dominant to wrinkled shape, and purple color is dominant to yellow color. What is the expected genotype ratio for the F2 generation of a dihybrid cross?

A student carries out an investigation using catalase and hydrogen peroxide. The student mixed the catalase and hydrogen peroxide and recorded the amount of bubbles produced at different temperatures. The graph of the result is provided. In this investigation, catalase was the [substance1] and hydrogen peroxide was the [substance2] The graph showed that catalase worked best at [temperature1]. According to the graph, approximately what [volume] of bubbles was produced at 20 degrees Celsius? (give your answer in mL)

Listed below are amounts of court income and salaries paid to the town justices for a certain town. All amounts are in thousands of dollars. Find the indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 99% confidence level with a court income of $800,000.

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person purchased a slot machine and tested it by playing it 1,117 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic ofχ2=11.516. Use a 0.025 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as expected? Find the test statistic[TS]? Find the critical value?[CV] Do you accept/reject?[acceptorreject] Write upto 3 decimal points
