Zeljko's father pays $55 each month.

The cost of the TV bought by Zeljko's father = $660

The payment for the TV is divided monthly for a year.

But one year = 12 months.

Therefore, the amount of money he will pay per month would be the total amount divided by 12, that is,

= 660/12

= $55

Therefore, Zeljko's father pays $55 each month.

Stells [14]

Answer:

B. The difference of the medians is about one-fourth the interquartile range of either data set

Step-by-step explanation:

Given the heights of preschool boys in cms

105.1 104.8 101.3 87 86.7 95 93.8 92.1 92.4 100

Arrange them in ascending order

86.7 87 92.1 92.4 93.8 95 100 101.3 104.8 105.1

Median = 93.8: Q1 = 87:Q3=101.3

IQR = Q3-Q1 = 4.3

Given the heights of preschool girls in cms

 85.2 90.3 99.6 98.6 97.5 101.7 102.9 89.4 107 92

Arrange them in ascending order

 85.2 89.4 90.3 92 97.5 98.6 99.6 101.7 102.9 107

Median = 97.5: Q1 = 89.4:Q3=101.7

IQR = 4.2

Differnce in the medians = 3.7

Diff in IQR = 0.1

B. The difference of the medians is about one-fourth the interquartile range of either data set because

0.4 = 4(0.1)

Suppose we purchase a larger bag of Skittles. Assume that this size bag always has 100 candies. In this particular bag 30 are gr
Mademuasel [1]

Answer:

Yes, this is surprising. Random samples with this much error are unusual.

Step-by-step explanation:

The expected proportion of green candies in the bag is p=0.20.

We have a sample with proportion p=0.3.

The amount of candies in the bag are 100.

We can calculate the probabilities of having 30 candies out of a sample of size n=100, if the proportion of the population is p=0.2.

This can be modeled by a binomial distribution with these parameters:

\mu=np=100*0.2=20\\\\\sigma=\sqrt{npq}=\sqrt{100*0.2*0.8}=\sqrt{16}=4

Then, the probability of having 30 or more candy in the bag is (applying the continuity factor):

z=(X-\mu)/\sigma=(29.5-20)/4=9.5/4=2.375\\\\\\P(X>30)=P(z>2.375)=0.00877\approx 0.01

There is too little probability (1%) of having 30 green candies in the bag.
