Astate meat inspector in iowa has been given the assignment of estimating the mean net weight of packages of ground chuck labeled "3 pounds." of course, he realizes that the weights cannot be precisely 3 pounds. a sample of 36 packages reveals the mean weight to be 3.01 pounds, with a standard deviation of 0.03 pound. what is the estimated population mean?

3.01

Step-by-step explanation:

We know that is the population mean unknown , then the sample mean is the best point estimate for population mean .

Let be the population mean weight of packages of ground ground chuck labeled "3 pounds."

Given : A sample of 36 packages reveals the mean weight to be 3.01 pounds.

i.e. sample mean = 3.01

Then, the estimated population mean should be 3.01.

Hence, the estimated population mean= 3.01

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
