Answer:

5\sqrt{7}

Step-by-step explanation:

\frac{30\sqrt{14} }{6\sqrt{2} }

Cancel out 6 in both numerator and denominator.

\frac{5\sqrt{14} }{\sqrt{2} } Rationalize the denominator of \frac{5\sqrt{14} }{\sqrt{2} } by multiplying the numerator and denominator by \sqrt{2}.

\frac{5\sqrt{14}\sqrt{2}  }{(\sqrt{2})^{2}  }

The square of  \sqrt{2} is 2

Factor 14=2 × 7. Rewrite the square root of the product \sqrt{2x7} as the product of square roots \sqrt{2}\sqrt{7}.

\frac{5\sqrt{2}\sqrt{7}\sqrt{2}   }{2}

Multiply \sqrt{2} and \sqrt{2} to get 2.

\frac{5x2\sqrt{7} }{2}

Cancel out 2 and 2.

5\sqrt{7}

Hope it helps and have a great day! =D

A company surveyed adult Americans about their consumer debt. They reported that 48% of Millennials (those born between 1980 and
sergeinik [125]

Answer:

We reject H₀ at 95 % of CI the group of Gen Xers who do not pay their credit card each month, is greater than this proportion for Millennians

Step-by-step explanation:

Sample proportion 1: Born between 1980 and 1996

sample size    n₁  = 450

p₁  =  0,48        p₁ = 48 %

x₁ = 0,48 * 450        x₁ = 216

Sample proportion 2:  Born between 1965 and 1971

sample size    n₂  = 300

p₂ =  0,60         p₂ = 60%

x₂  = 0,6* 300     x₂  = 180

Test Hypothesis:

Null Hypothesis                          H₀               p₂  =   p₁

Alternative Hypothesis              H                p₂  >  p₁

Samples both big enough to use the normal distribution as an approximation to the binomial distribution.

We assume  CI = 95 %   then significance level α   = 5 %  the alternative hypothesis tells us that we need to develop a one-tail test to the right.

z-score  is z(c)  for  α = 0,05       from z-table   z(c) = 1,64

To calculate z(s)

z(s)  =  ( p₂  -  p₁ ) / √ p*q ( 1 /n₁ + 1 / n₂)

p₂ - p₁  =  0,60  - 0,48

p₂ - p₁  =  0,12

p = ( x₁ + x₂ ) / n₁ + n₂

p = ( 216  + 300) / 450 + 300

p = 516 / 750     p = 0,688      then   q = 1 - p     q = 0,312

z(s) = 0,12 / √ 0,688*0,312* ( 1/450) + 1/ 300)

z(s) = 0,12 / √ 0,2146* ( 0,0022 + 0,0033)

z(s) = 0,12 / √ 0,001192

z(s) = 0,12/ 0,03452

z(s) = 3,47

Comparing |z(c)|   and |z(s)|

z(s) > z(c)

Then z(s) is in the rejection region. We reject H₀.

We can support the  claim that the proportion of the group Gen Xers who do not pay their credit card is greater than Millennians
