Consider testing the hypothesis H0: mu= 800 vs. H1: mu not identical to800. If the value of the test statistic z equals 1.75, then the p-value is

0.0802

Step-by-step explanation:

Calculation for the p-value

Based on the information given this is a two tailed test

Hence,

p(z< -1.75)= 0.0401

p(z> 1.75) = 0.0401

Now let calculate the p-value

p-value=2* 0.0401

p-value= 0.0802

Therefore If the value of the test statistic z equals 1.75 the p-value will be 0.0802

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
