Apublisher reports that 37% of their readers own a laptop. a marketing executive wants to test the claim that the percentage is actually different from the reported percentage. a random sample of 350 found that 30% of the readers owned a laptop. find the value of the test statistic. round your answer to two decimal places.

p(s)  = - 2.71

Step-by-step explanation:

Test of proportion

sample size       n  =  350

Publisher report             37 %      0,37

Sample proportion          30 %      0.30

p(s)  = [ ( p  -  p₀ ) /√(p₀q₀/n ]      ⇒  p(s)  = - 0.07*(18.70)/√(0.37)*(0.63)

p(s)  = - 1.3095/0.4828

p(s)  = - 2.71

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

hi! i think the answer is 1/2 : )
