A machine that is programmed to package 3.00 pounds of cereal in each cereal box is being tested for its accuracy. In a sample of 49 cereal boxes, the mean and the standard deviation are calculated as 3.05 pounds and 0.14 pound, respectively. b-1. Calculate the value of the test statistic

b-2. Find the p-value.

multiple choice 2

p-value < 0.01

p-value 0.10

0.05 p-value < 0.10

0.01 p-value < 0.02

0.02 p-value < 0.05
c-1. What is the conclusion at the 5% significance level?

multiple choice 3
Do not reject H0 since the p-value is smaller than significance level.
Do not reject H0 since the p-value is greater than significance level.
Reject H0 since the p-value is smaller than significance level.
Reject H0 since the p-value is greater than significance level.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
