An agricultural researcher wishes to see if a kelp extract prevents frost damage on tomato plants. Two similar small plots are going to be planted with the same variety of tomato. Both plots will be treated identically with the exception that the plants on plot 1 are going to be sprayed weekly with a kelp extract while the plants in plot 2 are not. Let p, and p, be the actual proportion of all tomatoes of this variety that would experience crop damage under the kelp and no kelp treatments respectively, when grown under conditions similar to those in the experiment. Which of the following 95% confidence intervals for p- p2 would indicate that there is a significant difference between the two treatments? Select one: a. (-0.279, -0.035) b. (-0.279, 0.035) C. (0.279, 0.350) d. Both a. and c.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Transcribed Image Text:An agricultural researcher wishes to see if a kelp extract prevents frost damage on tomato plants. Two similar small plots
are going to be planted with the same variety of tomato. Both plots will be treated identically with the exception that the
plants on plot 1 are going to be sprayed weekly with a kelp extract while the plants in plot 2 are not.
Let p, and p2 be the actual proportion of all tomatoes of this variety that would experience crop damage under the kelp
and no kelp treatments respectively, when grown under conditions similar to those in the experiment.
Which of the following 95% confidence intervals for p - p2 would indicate that there is a significant difference between
the two treatments?
Select one:
a. (-0.279, -0.035)
b. (-0.279, 0.035)
