Fran would like to estimate the mean amount of time it takes people in her town to travel to work,
The town's population is 150,000 and about 90,000 of those are working adults,
Which statements are true?
Select each correct answer,
The population of working adults is too large for using a sample to estimate the mean
of the entire group.
A larger sample of working adults will provide a better estimate of the true mean than a
smaller sample,
If she takes a random sample of the population of working adults in her town, the mean
for that group is likely close to the mean for the entire group.
There is no way to infer the value of the mean. She must collect data for all 90,000
working adults and calculate the mean,

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?

Given: p: 2x = 16 q: 3x – 4= 20 which is the converse of p - q? if 2x + 16, then 3x - 4 20. if 3x –4 +20, then 2x # 16. lf 2x = 16, then 3x - 4 = 20. lf 3x – 4= 20, then 2x = 16. o o
