Abag contains 12 pieces of candy, all the same size. four of the candies are lemon flavored. which approach would be best to find the probability of randomly drawing a lemon-flavored piece of candy? a. subjective approach b. classical approach c. relative frequency approach

Relative frequency approach

Step-by-step explanation:

In relative frequency of an event  is defined as the number of times that the event occurs during experimental trials, divided by the total number of trials conducted in the given event.

That is if there are total 9 boys in which 4 are from Us.

Then the probability of choosing a boy of Us= Number of boys from US/ total number of boys= 4/9

In our question, we have total  pieces of candy= 12

In which lemon-flavored piece of candy = 4

the probability of randomly drawing a lemon-flavored piece of candy= 4/12

= lemon-flavored piece of candy/ total  pieces of candy

Thus, we are using relative frequency approach for finding the probability.

Therefore, Option C is correct.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
