Determine whether the following statement regarding the hypothesistest for two population proportions is true or false.
murzikaleks [220]

Answer:

False

Step-by-step explanation:

Let p1 be the population proportion for the first population

and p2 be the population proportion for the second population

Then

H_{0} p1  = p2

H_{a} p1 ≠ p2

Test statistic can be found usin the equation:

z=\frac{p1-p2}{\sqrt{{p*(1-p)*(\frac{1}{n1} +\frac{1}{n2}) }}} where

  • p1 is the sample population proportion for the first population
  • p2 is the sample population proportion for the second population
  • p is the pool proportion of p1 and p2
  • n1 is the sample size of the first population
  • n2 is the sample size of the second population.

As |p1-p2| gets smaller, the value of the <em>test statistic</em> gets smaller. Thus the probability of its being extreme gets smaller. This means its p-value gets higher.

As the<em> p-value</em> gets higher, the null hypothesis is less likely be rejected.

Help!!!!!!!!!!!!!!!!!!!!!!!!!
torisob [31]

Answer:

53

Step-by-step explanation:

\frac{sin(56)}{78.6}  =  \frac{sin(90)}{ab}  \\  \\ absin(56) = sin(90) \times 78.6 \\  \\ ab =  \frac{sin(90) \times 78.6}{sin(56)}  \\ ab = 94.8 \\  \\  {x}^{2}   +  {78.6}^{2}  =  {94.8}^{2}  \\  {x}^{2}  =  {94.8}^{2}  -  {78.6}^{2}  \\  {x}^{2}  = 8987.04 - 6177.96 \\  {x}^{2}  = 2809.08 \\ x =  \sqrt{2809.08}  \\ x = 53
