After checking to ensure that the sample data follows the necessary condition for using the t-procedure, we use minitab to get a 90% confidence interval to estimate mu. we find it to be (118.51 ounces, 124.29 ounces). what does this interval tell us?

the 90% confidence interval to estimate mu = (118.51 ounces, 124.29 ounces) means that out of all the data 90% of the sample has the weight between the range 118.51 ounces and 124.29 ounces.

Step-by-step explanation:

Data provided in the question:

Confidence level = 90%

90% confidence interval to estimate mu = (118.51 ounces, 124.29 ounces)

Now,

The confidence level tells us that out of all the value of the sample the given percentage of confidence level lies within the calculated interval.

Here in the given question,

the 90% confidence interval to estimate mu = (118.51 ounces, 124.29 ounces) means that out of all the data 90% of the sample has the weight between the range 118.51 ounces and 124.29 ounces.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
