Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 12 boxes. It is reasonable to assume that the population is approximately normal. 13.03 14.98 13.12 13.13 13.11 13.03 13.16 14.98 13.06 13.05 13.12 13.13 2. Sand data Part: 0/2 WS Part 1 of 2 (a) Construct a 95% confidence interval for the mean weight. Round the answers to at least three decimal places. A 95% confidence interval for the mean weight is

95% Confidence interval:  (12.93, 13.87)      

Step-by-step explanation:

We are given the following in the question:

13.03, 14.98, 13.12, 13.13, 13.11, 13.03, 13.16, 14.98, 13.06, 13.05, 13.12, 13.13

Formula:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences = 5.94

95% Confidence interval:  

Putting the values, we get,  

goog may have it for you

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
