a. at most 7 Round your answer to four decimal places. P( at most 7)= Enter you answer; P(at most 7) b. 4 to 6 Round your answer to four decimal places. P(4 to 6)= Enter you answer; P(4 to 6) c. at least 7 Round your answer to four decimal places. P( at least 7)= Enter you answer; P(at least 7)
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.
According to a Wakefield Research survey of adult women, 50% of the women said that they had tried five or more diets in their lifetime (USA TODAY, June 21, 2011). Suppose that this result is true for the current population of adult women. A random sample of 11 adult women is selected. Use the binomial probabilities table or technology to find the probability that the number of women in this sample of 11 who had tried five or more diets in their lifetime is
Round your answer to four decimal places.
P( at most 7)= Enter you answer; P(at most 7)
b. 4 to 6
Round your answer to four decimal places.
P(4 to 6)= Enter you answer; P(4 to 6)
c. at least 7
Round your answer to four decimal places.
P( at least 7)= Enter you answer; P(at least 7)
The probability that the number of women in this sample of 11 who had tried five or more diets in their lifetime is at most 7 will be:
Excel formula BINOMDIST() is used to calculate the probabilities
P( at most 7)= 0.8867
