Houseflies have pretty short lifespans. Males of a certain species have lifespans that are strongly skewed to the

right with a mean of 26 days and a standard deviation of 12 days. A biologist collects a random sample of 9 of

these male houseflies and observes them to calculate the sample mean lifespan.

What is the probability that the mean lifespan from the sample of 9 houseflies 2 is less than 24 days?

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
