a box plot
Step-by-step explanation:
Given the number of employees at her company is 685

If she chooses the box lot, which means that she wants to displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.
=> So it is the best fit for her choice.
If she chooses histogram, it means that she wants to group numbers into ranges to identify the underlying frequency distribution (shape) of a set of continuous data

Answer: The sample size would be needed = 385
Step-by-step explanation:
Let p be the prior population proportion.
Margin of error = E
When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> = 
, where z* = critical value for given confidence interval.
Here z* for 95% confidence level is 1.96.
E=5%=0.05
Then 
Hence, the sample size would be needed = 385
Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
= 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
= 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
= 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3
