Answer: (2.54,6.86)
Step-by-step explanation:
Given : A random sample of 10 parking meters in a beach community showed the following incomes for a day.
We assume the incomes are normally distributed.
Mean income : 
Standard deviation : 


The confidence interval for the population mean (for sample size <30) is given by :-

Given significance level : 
Critical value : 
We assume that the population is normally distributed.
Now, the 95% confidence interval for the true mean will be :-

Hence, 95% confidence interval for the true mean= (2.54,6.86)
Answer:
event A is dependent on event B since roll 3 will result if you select a face card
Flourish- 120x
Green Thumb- (70x)=1600
Flourish- 120*35= $4200
Green Thumb- (70*35)+1600= $4050
It would be less expensive to hire Green Thumb Landscapers. There is a $150 difference between the two
It would take 32 hours of work for the cost to be the same for both companies<span />
280 right handed gloves. First, we'd need to find out the amount of left handed gloves. We do this by multiplying 0.3 (which is basically 30%) by the total number of gloves. This is because we are finding out 30% of the 400 gloves, and "of" represents multiplication. We get 120. Then, we subtract that number from 400 to get the amount of right handed gloves, which is 280. hope this helps :)
