Select the correct comparison.
Delicious77 [7]

The true comparison is the typical value is greater in set A. The spread is greater in set B.

<h3>What is the true comparison?</h3>

Spread is used to measure the variability of a data set. Range can be used to measure spread. Range is the difference between the largest number and the smallest number in the dataset.

  • Spread of set A =  7 - 5 = 2
  • Spread of set B = 8 - 1 = 7

The median can be used to measure the typical value of the dataset. Median is the number at the center of the data set.

  • Median of set A = 6
  • Median of set B = 4

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t
Thepotemich [5.8K]

Answer:

The probability that exactly 12 buyers would prefer green

=0.00555

Step-by-step explanation:

We are given that

p=50%=50/100=0.50

n=14

We have to find the probability that exactly 12 buyers would prefer green.

q=1-p

q=1-0.50=0.50

Using binomial distribution formula

P(X=x)=nC_r p^r q^{n-r}

P(x=12)=14C_{12}(0.50)^{12}(0.50)^{14-12}

P(x=12)=14C_{12}(0.50)^{12}(0.50)^2

P(x=12)=14C_{12}(0.50)^{14}

P(x=12)=\frac{14!}{12!2!}(0.50)^{14}

P(x=12)=\frac{14\times 13\times 12!}{12!2\times 1}(0.50)^{14}

P(x=12)=91\cdot (0.50)^{14}

P(x=12)=0.00555

Hence, the probability that exactly 12 buyers would prefer green

=0.00555
