Let p equal the proportion of triathletes who suffered a training-related overuse injury during the past year. Out of 330 triathletes who responded to a survey, 167 indicated that they had suffered such an injury during the past year. a) Use these data to give a point estimate of p. b)Use these data to find a 90% confidence interval for p. c) Do you think that the 330 triathletes who responded to the survey may be considered a random sample from the population of triathletes?
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.
Let p equal the proportion of triathletes who suffered a training-related overuse injury during the past year. Out of 330 triathletes who responded to a survey, 167 indicated that they had suffered such an injury during the past year.
a) Use these data to give a point estimate of p.
b)Use these data to find a 90% confidence interval for p.
c) Do you think that the 330 triathletes who responded to the survey may be considered a random sample from the population of triathletes?
