Answer:
The confidence interval for this case would be (216.589, 223.411)
Step-by-step explanation:
Information given
represent the sample mean
population mean
s=12 represent the sample standard deviation
n=50 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.95 or 95%, the significance is 
and 
, the critical value for this case is 
And replacing we got:
The confidence interval for this case would be (216.589, 223.411)
Answer:
first person has a chance of 7/28 or 1/4
The second = 6/27 or 2/9
The third = 5/26
And the fourth = 4/25
multiplying these together you get 4 / 2340=
1/585
or 0.17%
Answer
I assume you're talking about 6-7, so on the left lines, you already did it, you just regularly subtract the numbers, and then on the right lines, you round the first problem to the nearest ten, remember five and up, round up, so for question 6 the new number model would be 90-40=50. since 93 rounds down to 90 and 38 rounds up to 40. continue to do that and write the entire model AND answer on the line to the right. hope this helps
