A school’s yearbook committee had many meetings last month the line plot summarizes how long each meeting lasted

kipiarov [429]

On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.

If its for any other number that you do not know, you can list as a proportion:

1/4 = x/60 (1 and x are on the top of the fractions)

Cross multiply: 1 * 60 = 60

Then divide by the number on the opposite corner of x: 60/4

x = 15

the manager of a grocery store has taken a random sample of 100 customers the average length of time it took these 100 customers

lora16 [44]

Answer:

with a .95 probability, the sample mean will provide a margin of error 0.196

Step-by-step explanation:

margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in the .95 confidence level (1.96)

s is the population standard deviation (1 min.)

N is the sample size (100)

ME= $\frac{1.96*1}{\sqrt{100} }$ =0.196

95% confidence interval for check-out time would be 3 ±0.196 min
