Heather runs a successful lawn-mowing business. She would like to estimate the true mean amount of time it takes for her employees to mow a lawn. To do so, she selects a random sample of 30 customers and records the time it takes
the employees to mow their lawns. The 90% confidence interval for the true mean time it takes for her employees to
mow a lawn is 40-55 minutes. Which of the following would decrease the width of the interval?
O selecting another sample
O increasing the sample size
O decreasing the sample size
O increasing the confidence level

answer: huh

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
