Kendra surveyed a random sample of 100 members of a local gym. she found that 40% of the gym members surveyed had taken a yoga class. kendra wanted to know if it is plausible that 50% of the entire population of gym members had taken a yoga class. kendra performed 100 trials of a simulation. each trial simulated a sample of 100 gym members under the assumption that 50% of the population had taken a yoga class. the dot plot shows the results of the simulations. what is the best conclusion for kendra to make based on the data?
a. it is not plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is unlikely.
b. it is not plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is likely.
c. it is plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is unlikely.
d. it is plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is likely.

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
