MatroZZZ [7]

Answer:

Step-by-step explanation:

To solve using completing square, we need to write the equation as x2+3x=17.

The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4

The equation then becomes x2+3x+(9/4)=17+(9/4).

Solving it further will get you the final answer

Ainat [17]

Answer:

The test statistic Z = 3.125

Step-by-step explanation:

Given Population proportion P = 0.25

Given sample size 'n' = 696

Sample proportion 'p⁻' = 0.30

Test statistic

$Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.30-0.25}{\sqrt{\frac{0.25 X 0.75}{696} } } = 3.125$

Final answer:-

The test statistic Z = 3.125
