Answer:

A=30,32,44,48

B=22,34

intersect=26

numbers going outside is 24,28,36,38,40,42,46

b) 1/14

Step-by-step explanation:

a)The numbers that will go into the A bracket will be 30,32,44 and 48. The numbers that will go into the B bracket will be 22 and 34. The number that will go into the intersect will only be 26. And finally the numbers going on the outside of the venn diagram will be 24,28,36,38,40,42,46.

Answer:

This is strong evidence that more than 2% get damaged

Step-by-step explanation:

The company goal is to keep the proportion of damaged machines below 2%

$H_o: p = 0.02$

$H_a: p > 0.02$

One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents

So, x = 6

n = 66

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{6}{66}$

Formula : $z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$z=\frac{\frac{6}{66}-0.02}{\sqrt{\frac{0.02(1-0.02)}{66}}}$

$z=4.114$

So, the value of test statistic is 4.114

2) What is the P-value of the test statistic?

So, p value using calculator = .00002

p value < α

So, we accept the alternate hypothesis

So, This is strong evidence that more than 2% get damaged

Snezhnost [94]

12 $x$ = 400

$x$ = $\frac{400}{12}$

15 $x$ = 15 * $\frac{400}{12}$

$x$ = 500.

∴ 500 people took the survey
