Step-by-step explanation:
The method applied in this scenario is called simple random sampling. A sample of 100 customers is chosen from a larger population of customers and each customer has the same chance of being selected for the survey at any given time. Also, the chance of selecting 100 customers from each store is the same during the sampling process. The order of sampling at each store does not follow a certain order, thus, It is different from systematic random sampling.
Travel at the speeds of 65 miles per hour to drive the distance of 310 miles (if the speed in which the person in question is traveling at the same speed) =
310 divided by 65 =
= 4 and
hours
since it is "traveled distance = speed multiplied by time it takes
Answer:

Step-by-step explanation:
For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.
Here,
normalcdf(-100,1.25) = 0.894
This same result could be obtained using a table of z-scores.
