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)

Step-by-step explanation:
y is NOT a function of x because there is not a unique y for each x.
The vertical line through these three points is
x = 3
Area of square; 7 * 7 = 49
area of triangle = 1/2 (7 * 3) = 21/2 = 10.5
so total= 49 + 10.5 = 59.5
