Write an equation for the line through the point (7, 7) with slope 5 in point-slope form y = y0+m(x-x0)
Murljashka [212]

Answer:

y = 5x - 28

Step-by-step explanation:

y - y1 = m(x - x1)

y - 7 = 5(x - 7)

y - 7 = 5x - 35

add 7 to both sides to get rid of - 7 --> y = 5x -35 + 7

You are testing the null hypothesis that the population proportion equals .45, using data you collected from a sample of 100 adu
Sedaia [141]

Answer:

z=\frac{0.3 -0.45}{\sqrt{\frac{0.45(1-0.45)}{100}}}=-3.015  

Step-by-step explanation:

Data given and notation

n=100 represent the random sample taken

\hat p=0.3 estimated proportion of interest

p_o=0.45 is the value that we want to test

\alpha represent the significance level

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that the true proportion is 0.45.:  

Null hypothesis:p=0.45  

Alternative hypothesis:p \neq 0.45  

When we conduct a proportion test we need to use the z statistic, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The One-Sample Proportion Test is used to assess whether a population proportion \hat p is significantly different from a hypothesized value p_o.

Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

z=\frac{0.3 -0.45}{\sqrt{\frac{0.45(1-0.45)}{100}}}=-3.015
