Suppose that an independent research company was tasked with testing the validity of complaints against a pesticide manufacturing firm for under-filling their 20 lb bags of pesticide. Past experience has shown that the amount of pesticide
dispensed by the machines that fill the bags follows a normal distribution with a mean of 20 lb and a standard deviation of
0.6 lb.
To verify the validity of the complaints, a researcher randomly selected 16 of the firm's 20 lb pesticide bags and recorded the
following weights.
19.81, 18.54, 19.94, 18.52, 18.5, 18.72, 19.38, 19.37, 19.08, 19.1, 18.54,20.27, 20.23, 19.77, 19.14, 20.31

The mean weight of the 16 bags collected was 19.326 lb. Calculate the value of the one-sample z- statistic.
Give your answer precise to three decimal places.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

what are the statments

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
