Slices of pizza for a certain brand of pizza have a mass that is approximately normally distributed with a mean of 68.3 grams and a standard deviation of 1.97 grams.
a) For samples of size 16 pizza slices, what is the standard deviation for the sampling distribution of the
sample mean?
b) What is the probability of finding a random slice of pizza with a mass of less than 68 grams?
c) What is the probability of finding a 16 random slices of pizza with a mean mass of less than 68 grams?
d) What sample mean (for a sample of size 16) would represent the bottom 15% (the 15th percentile)?
grams

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
