A χ2 goodness-of-fit test is performed on a random sample of a bag of 30 Skittles® to determine whether the proportion of each f

lavor (strawberry, orange, lemon, lime, and grape) is equal to the claimed amount (20% of each flavor). The χ2 statistic is determined to be 10.20. What is the p-value for this test? (4 points)
A 0.001 < p < 0.005

B 0.02 < p < 0.025

C 0.025 < p < 0.05

D 0.10 < p < 0.15

E 0.05 < p < 0.10

Answer:

C. 0.025 < p < 0.05

Step-by-step explanation:

The \chi^2 goodness-of-fit test parameters are presented here as follows;

The number of Skittles in the bag = 30 Skittles

The different flavors in the bag of Skittles = Strawberry, orange, lemon, lime, and grape

The number of different flavors, n = 5 flavors

The \chi^2 statistic = 10.20

Therefore, the degrees of freedom, d.f. = n - 1 = 5 - 1 = 4

Using the chi-square (\chi^2) distribution table,  we have;

The probability at 4 degrees of freedom for a \chi^2 statistic of 10.20 is between 0.025 and 0.05

Therefore, we get;

The probability (P > 10.20) = 0.025 < p < 0.05.

Question 4 please. I will mark brainliest!! i would at least like the equation of the graph thank you
Anestetic [448]

Answer:

a. -3 < x ≤ 5

b. -3 ≤ y < 3

c.  (0, 0)

d. x = -3, x = 1, x = 5

e. -3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. (-1, -1), and (3, -3)

Step-by-step explanation:

a. The domain of a function is the set of the possible independent variable values which is -3 < x ≤ 5

b. The range of a function is the set of the possible values of the dependent variable which is -3 ≤ y < 3

c. The y-intercept is the point the graph crosses the y-axis

The y-intercept in the graph is the point (0, 0)

d. f(x) ≥ 0  when x = -3, x = 1, x = 5

f(x) ≥ 0 over the following range; -3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5

e. The intervals over which f(x) is decreasing are;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums where f(x) has the minimum values are;

(-1, -1), and (3, -3)
