A survey of a random sample of 210 male teens and 228 female teens, ages 13 years to 17 years, found that 122 of the male teens and 160 of the female teens brush their teeth at least twice a day. if there is no difference between the proportions in the population of all male and female teens ages 13 years to 17 years who brush their teeth at least twice a day, approximately how many males and females in the sample would be expected to brush their teeth at least twice a day?.

Answers

Answer 1

The number of expected males and females to brush their teeth at least twice a day are : 135 males and 147 females.

What is proportion?

Proportion refers to the part of the things or numbers which are comparable with each other. For example: the weight of the Rahul is 70kgs and weight of the Mohan is 100kgs. Thus the Mohan's weight is greater than the Rahul's weight.

The pooled samples by combining the sample proportion to that of the successes in the each samples and combining the sample sizes.

P^ = (122+160)/(210+228)= 282/438

Then multiply this pooled sample with the two sample sizes:

Expected males = n1*^p = 210(282/438) = 135.21

expected females =n2*^p = 228(282/438) = 146.79

Thus the expected numbers of males are 135 and expected numbers of females are 147.

What are low-cost vehicles in India?

The term "fuel economy" refers to the correlation between a vehicle's distance traveled and its low-cost  consumption. Consumption can be calculated as either the amount of fuel used to travel a specific distance or the distance traveled for each unit of low-cost used.

Anything listed as less than 6 l/100 km or greater than 16.5 l/l is considered to be generally excellent. Liters per 100 kilometers is the standard unit of measurement and is also the most used. This is the quantity of fuel needed for a 100-kilometer drive in the car.

The biggest difference between an low-cost  car and a little car is size. Despite the fact that renting and operating both kinds of vehicles can often be relatively affordable and both provide outstanding fuel efficiency.

Thus, option C is correct.

On a boiling hot day near the end of the summer, Nick arrives for lunch at the Buchannan's' house; Gatsby and Jordan have also been invited. In the dining room, Daisy pays Gatsby a compliment that makes clear her love for him, and, when Tom notices this, he insists they drive into town. Daisy and Gatsby leave in Tom's blue coupe, while Tom drives Jordan and Nick in Gatsby's garish yellow car. On the way, Tom stops for gas at George Wilson's garage in the valley of ashes, and Wilson tells Tom that he is planning to move west with Myrtle as soon as he can raise the money.
