Answer:
For example, the function does not have a y-intercept of (0, 1). To prove this, let's make x=0, and if the value of 'y' is different from 1, then, the graph does nt have a y-intercept of (0,1):
⇒
⇒
Therefore, the y-intercept is at (0, 0) not (0, 1).
Answer: (39.424, 61.576)
Step-by-step explanation:
When population standard deviation() unknown ,The confidence interval for population mean is given by :-
, where n= Sample size
= sample mean.
s= sample standard deviation
= Critical t-value (two-tailed)
Given : n= 15
Degree of freedom= 14 [df=n-1]
Significance level =
For and df = 14, the critical t-values :
Then the 95% confidence interval for population mean will be :
Hence, a 95% confidence interval for the average amount its credit card customers spent on their first visit to the chain's new store in the mall. : (39.424, 61.576)
