Answer:C
Step-by-step explanation:
The correct answer is c. To carry out this calculation, we begin by describing the sampling distribution of the sample proportion. The sample size is n=50 and the population proportion of teachers who made an apparel purchase is .56. Shape: because np=(50)(.56)=28 and n(1-p)=(50)(.44) are both at least 10, the shape of the sampling distribution of the population proportion is approximately normal. Center: p=.56. Variability: the standard deviation of the sample proportion is approximately .0702. normalcdf(loser: .6, upper: 1000, mean: .56, SD: .0702)=.284.
Answer:
2.17
Answer and Explanation:
The critical value of z for 97% confidence interval is 2.17, which is obtained by using a z score table, that is: {eq}P(-2.17 < Z <...
Answer:
D. y= 2/3x-2
Step-by-step explanation:
y=6-2x/-3
-2+2/3x
2/3x-2=y
M = 98 = 7×K
98/7 = 7×K/7 = K
The appropriate choice is
d. 7x=98. Divide both sides by 7. Kendall had $14.
Answer:
Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.
(a + b) + c = a + (b + c)
Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.
