Answer:
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
Step-by-step explanation:
We take the estimate from the website, and expand for all buyers, to find the proportion that use their smartphones.
400 users of the website were randomly sampled from the existing database and 180 were found to have used their smart phones.
180/400 = 0.45
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
Square root of 121 is 11.

A side of the original square is 4 feet.
Answer:
Option 4 is correct
Step-by-step explanation:
Here, we want to select from the options, the dataset that is represented on the histogram
From what we have in the question, there is a range from 60 to 100
Also, there are no terms between 70 and 80
option 1 is wrong as we can see terms between 70 and 80
option 2 is also wrong for this reason
option 3 is incorrect ; looking at the frequency, the numbers between 60 and 70 should be 5 only and we have 6 in that set
Option 4 is the correct answer
