Answer:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
the sample size
represent the sample mean
We want to find the margin of error for the confidence interval for the population mean and we know that is given by:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

9 - 6 is 3
they all skip by threes?
hope that helps
The answer in a fraction format is 2/9 or decimal format will be 0.222222222
Answer:
Theta = 52.1
Step-by-step explanation:
sin theta = opp / hyp
sin theta = 15/19
Take the inverse sin of each side
sin^-1 sin theta = sin^1- (15/19)
theta =52.13635364
To the nearest tenth
Theta = 52.1
X=-5 and y=1
you would replace the letter x or y with zero to find the intercept.
