Amajor blu-ray rental chain is considering opening a new store in an area that currently does not have any such stores. the chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with blu-ray players. it conducts a telephone poll of 300 randomly selected households in the area and finds that 96 have blu-ray players. the value of the test statistic in this problem is approximately equal to
(a) 2.8
(b) 2.6
(c) 1.3
(d) 1.94

(A) 2.8

Step-by-step explanation:

Given : The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.

i.e. Population proportion :

Also, It conducts a telephone poll of 300 randomly selected households in the area and finds that 96 have Blu-ray players.

i.e. Sample proportion :

Test statistic for proportion:

i.e  

Thus, the value of the test statistic in this problem is approximately equal to 2.8

Hence, the correct answer is option (A).

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
