A consumer electronics company is comparing the brightness of two different types of picture tubes for use in its television set

puteri [66]

Answer:

The answer is "0.7794".

Step-by-step explanation:

Please find the complete question in the attached file.

Given:

$\to n_{1}=n_{2}=25\\\\$

Hypotheses:

$\to H_{0}:\mu_{B}-\mu_{A}\geq 0\\\\\to H_{a}:\mu_{B}-\mu_{A}< 0\\\\$

Testing statistics:

$\to z=\frac{(\bar{x}_{B}-\bar{x}_{A})-(\mu_{B}-\mu_{A})}{\sqrt{\frac{\sigma^{2}_{B}}{n_{1}}+\frac{\sigma^{2}_{A}}{n_{2}}}}=\frac{3.5-(0)}{\sqrt{\frac{16^{2}}{25}+\frac{16^{2}}{25}}}=0.77$

The test is done just so the p-value of a test is

$\to p-value = P(z < 0.77) = 0.7794$

Because the p-value of the management is large, type B can take it.

using your knowledge of cross products how would you solve for x in the following pair of equivalent fractions 7 over x equals 2

Naddika [18.5K]

Use cross multiplication so you have

7/x = 2/4

multiple 7 and 4 to get 28 and multiply x and 2 to get 2x and set them equal to each other

so your new equation is 2x=28 and then you just need to solve for x

The answer is x=14
