Plz help<br> why is box and whisker plot a useful way to view data. explain plz

natka813 [3]

Okay so think of it like this, You have the numbers 1,5,8,9,15. So you have the first "Whisker" and that stands for the lower observation which is 1. Then you have the first part of the box which is the firsrt quartile 5. The you have the middle of the box which is the median easy way to remember that is meddle middle, And the median is 8. Then you have your third quartile which 9. Then you have your greatest quartile, 15. And that is your box and whisker plot. Hope this helped!

If mWP= 56° and mKA= 162°, find m E.

inn [45]

Answer:

m<E = 1/2 ( WP - KA )

m<E = 1/2 ( 162 -56 )

m<E = 1/2 (106)

m<E = 53

32% of U.S. adults say they are more likely to make purchases during a sales tax holiday. You randomly select 10 adults. Find t

garri49 [273]

Answer:

$a. \ 0.2107\\\\b.\ 0.6727\\\\c.\ 0.8157$

Step-by-step explanation:

a. Our random variable follows a binomial distribution which is defined as:

$P(X=x)={n \choose x } \times p^x \times (1-p)^n^-^x$ where $p$ is the probability of success, $n$ the sample size and $x$ the random variable.

-Given that $p=0.32$ , $n=10$ what's $P(X=2):$

$P(X=2)={10\choose 2}\times 0.32^2 \times (1-0.32)^8\\=0.2107$

Hence, the probability of exactly two is 0.2107

b. The probability that more than two adults are more likely to make purchases during a sales tax holiday is given by:

$P(X>2)=1-P(X=0)-P(X=1)-P(X=2)\\=1-{10\choose 2}\times 0.32^2 \times (1-0.32)^8-{10\choose 1}\times 0.32^1 \times (1-0.32)^9-{10\choose 0}\times 0.32^0 \times (1-0.32)^1^0\\=1-0.2107-0.0995-0.0211\\=0.6727$

Hence the probability of more that two adult purchases is 0.6727

c. The probability that the number of adults who say they are more likely to make purchases between 2 and 5 is obtain by summing the the probabilities

p(x=2)+p(x=3)+p(x=4)+p(x=5).

-From b above, we already have p(x=2)=0.2107. Therefore:

$P(2\leq X\leq 5)=P(X=2)+P(X=3)+P(X=4)+P(X=5)\\=0.2107+{10\choose 3}\times 0.32^3 \times (1-0.32)^7+{10\choose 4}\times 0.32^4 \times (1-0.32)^6+{10\choose 5}\times 0.32^5 \times (1-0.32)^5\\=0.2107+0.2644+0.2177+0.1229\\=0.8157$

-Hence the probability of between two and five is 0.8157
