Answer:
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 22.455 - 10.167 = 12.288
The upper end of the interval is the mean added to M. So it is 22.455 + 10.167 = 32.622
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).
Answer:
The number of people who like winter season is 1000.
Step-by-step explanation:
Event event correspond to a set in the Venn diagram, and we use it to find the percentages.
I am going to say that:
Event A: Like summer season
Event B: Like winter season.
55% like summer season
This means that 
20% like winter season
This means that 
40% don't like both seasons
This means that 100% - 40% = 60% like at least one, which means that 
Proportion who like both:
This is 
. The measures are related by the following equation:
Using what we have
750 like both seasons.
This is 15% of the sample. So the total number of people is t, for which:
20% like winter season
Out of 5000. So
0.2*5000 = 1000
The number of people who like winter season is 1000.
