Heather, a sociology major is interested in studying mass media topics. She is particularly interested in the percentage of mass
Serhud [2]

Answer:

Null hypothesis:p=0.72  

Alternative hypothesis:p \neq 0.72

p_v = 2*P(|z|>z_{calc})

And the best answer for this case is:

C. p-value

Step-by-step explanation:

Data given and notation

n represent the random sample taken

\hat p estimated proportion of interest

p_o=0.72 is the value that we want to test

\alpha=0.05 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 i 0.72 or no.:  

Null hypothesis:p=0.72  

Alternative hypothesis:p \neq 0.72  

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.

For this case the only probability that can be calculated from the statistic calculated is the p value given by:

p_v = 2*P(|z|>z_{calc})

And the best answer for this case is:

C. p-value

Mr. Rose spent $63 for a sport jacket and a pair of slacks. If the jacket cost $33 more than the slacks, how much did he pay for
alexdok [17]
J + s = 63 and j - s = 33 because if the jacket cost 33 more than the slacks then you start with the jacket and subtract the slacks which are 33 less than the jacket you have 33.

\frac { 6 ^ { n + 2 } - 6 ^ { n } } { 6 ^ { n + 1 } + 6 ^ { n } }
Sindrei [870]

Answer:

5

Step-by-step explanation:

Given expression:

\dfrac{6^{n+2}-6^n}{6^{n+1}+6^n}

\textsf{Apply exponent rule} \quad a^{b+c}=a^b \cdot a^c

\implies \dfrac{6^n6^2-6^n}{6^n6^1+6^n}

Factor:

\implies \dfrac{6^n(6^2-1)}{6^n(6^1+1)}

Cancel 6^n :

\implies \dfrac{(6^2-1)}{(6^1+1)}

Simplify:

\implies \dfrac{36-1}{6+1}

\implies \dfrac{35}{7}

\implies 5
