Penny Weights, use the weights of the post 1983 pennies to construct a 98% confidence interval estimate of the standard deviatio
Ronch [10]

Answer:

c. 0.1391 < Ï < 0.2311

Step-by-step explanation:

The formula for Confidence Interval is given as:

Mean ± z × Standard deviation/√n

Z score for 98% confidence interval = 2.326

Mean = Significance level = 100% - 98%

= 2% = 0.02

Standard deviation = S=0.0165

n= 37

Hence,

Confidence Interval =

0.02 ± 2.326 × 0.0165/√37

0.02 ± 0.0063094687

Confidence Interval

0.02 - 0.0063094687

= 0.1391

0.02 ± 0.0063094687

= 0.2311

Hence, the Confidence Interval = (0.1391, 0.2311)

= c. 0.1391 < Ï < 0.2311

The total cost, C, for running an advertisement in a local newspaper, The Free Press, is made up of an initial cost of $12 plus
allochka39001 [22]

There is no clear question here, however, the plan for the local newspaper, if the plan is long-term, is more comfortable for the consumers, but less comfortable if it is short-term.

Using a sample size of two days.

- For the local newspaper, we have

($5 × 2) + ($12) = $22

- For the rivals, we have

$8 × 2 = $16

Using a sample size of one hundred days.

- For the local newspaper, we have

($5 × 100) + ($12) = $512

- For the rivals, we have

$8 × 100 = $800
