Theresa really loves orange-flavored Fruity Tooty candies, but there always seems to be a lot of cherry-flavored candies in each bag. To determine whether this is because cherry candies are so popular or because each bag contains fewer orange candies, Theresa randomly picks a Fruity Tooty candy from her bag, records its flavor, and places it back in the bag. Each bag contains a mixture of cherry, grape, apple, lemon, and orange flavors.Which statement about Theresa's distribution of sample proportions is true?a.)The count of drawing an orange candy is not a binomial distribution.b.)The sample proportion of cherry candies has a binomial distribution.c.)The distribution of lemon candy can be modeled as normal if Theresa picks candies 12 times.d.)The distribution of the count of picking an apple candy cannot be modeled as approximately normal if Theresa picks candies over 300 times.
Question
Theresa really loves orange-flavored Fruity Tooty candies, but there always seems to be a lot of cherry-flavored candies in each bag. To determine whether this is because cherry candies are so popular or because each bag contains fewer orange candies, Theresa randomly picks a Fruity Tooty candy from her bag, records its flavor, and places it back in the bag. Each bag contains a mixture of cherry, grape, apple, lemon, and orange flavors.Which statement about Theresa's distribution of sample proportions is true?a.)The count of drawing an orange candy is not a binomial distribution.b.)The sample proportion of cherry candies has a binomial distribution.c.)The distribution of lemon candy can be modeled as normal if Theresa picks candies 12 times.d.)The distribution of the count of picking an apple candy cannot be modeled as approximately normal if Theresa picks candies over 300 times.
Solution
The correct answer is a.) The count of drawing an orange candy is not a binomial distribution.
This is because a binomial distribution has two possible outcomes, often referred to as "success" and "failure". In this case, there are five possible outcomes (cherry, grape, apple, lemon, and orange), so the distribution of drawing an orange candy cannot be a binomial distribution.
The other options are incorrect because:
b.) The sample proportion of cherry candies could have a binomial distribution if we define "success" as drawing a cherry candy and "failure" as not drawing a cherry candy. However, the question does not provide enough information to determine this.
c.) The distribution of lemon candy can be modeled as normal if Theresa picks candies 12 times. This statement is incorrect because the normal approximation to the bin

A certain manufacturer claims that they produce 50% brown candies. Sam plans to buy a large family size bag of these candies and Kerry plans to buy a small fun size bag. Which bag is more likely to have more than 70% brown candies?Group of answer choicesSam, because there are more candies, so his bag can have more brown candies.Sam, Because there is more variability in the proportion of browns among larger samples.Kerry, because there is more variability in the proportion of browns among smaller samples.Kerry, because most small bags will have more than 50% brown candies.Both have the same chance because they are both random samples.
Lauren has a bag that contains strawberry chews, lemon chews, and peach chews. She performs an experiment. Lauren randomly removes a chew from the bag, records the result, and returns the chew to the bag. Lauren performs the experiment 45 times. The results are shown below:A strawberry chew was selected 13 times.A lemon chew was selected 11 times.A peach chew was selected 21 times.Based on these results, express the probability that the next chew Lauren removes from the bag will be a flavor other than peach as a fraction in simplest form.
