In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times landing tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times. Let pp = the true proportion of times a dime will land tails up and pp = the true proportion of times a penny will land tails up. Whích of the following is the correct standardized test statistic and P- value for the hypotheses, H Po-Pp-0 and H, Po-Pp<0?

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:In a statistics activity, students are asked to spin a penny and a dime and determine the proportion of times that
each lands with tails up. The students believe that since a dime is lighter, it will have a lower proportion of times
landing tails up compared to the penny. The students are instructed to spin the penny and the dime 30 times and
record the number of times each lands tails up. For one student, the penny lands tails side up 18 times, and the
dime lands tails side up 20 times. Let pp = the true proportion of times a dime will land tails up and pp = the true
proportion of times a penny will land tails up. Which of the following is the correct standardized test statistic and P-
value for the hypotheses, H Pp-P,0 and H Po-P,<0?
