\qquad \qquad  \bf \huge\star \:  \:  \large{  \underline{Answer} }  \huge \:  \: \star

  • Angle x = 29°

\textsf{  \underline{\underline{Steps to solve the problem} }:}

  • \sf \: \angle x + 109 + 42  = 180

( makes co - interior angles, since the two lines are parallel )

  • \sf \:  \angle \: x + 151 = 180

  • \sf \:  \angle x =18 0 - 151

  • \sf \: \angle x = 29 \degree

\qquad \large \sf {Conclusion}  :

  • x = 29°

Three-sevenths of a number is 21. Find the number
ruslelena [56]
You can set up a proportion that looks like 3/7 = x/21. X being the number that you are trying to find. Seven goes into 21 three times. So multiply 3 also by that 3 to get 9. So three sevenths of twenty-one is 9.

An article presents a study of health outcomes in women with symptoms of heart disease. In a sample of 115 women whose test resu
My name is Ann [436]

Answer:

z(s) is in the rejection region we reject H₀     μ₁  = μ₂  and support the claim that at CI 95 % the means of the two groups differs

Step-by-step explanation:

Sample 1:

Sise sample   n₁  =  115

μ₁  = 169,9 mmHg

σ₁  = 24,8 mmHg

Sample 2:

Sise sample   n₂  =  235

μ₂  = 163,3 mmHg

σ₂  = 25,8 mmHg

We can develop a test hypothesis for differences in means to investigate if the mean peak systolic blood pressure differs between these two groups

We will choose CI = 95 %   then significance level  α  = 5 %

α = 0,05     α/2 = 0,025

z(c) for 0,025 is from z-table   z(c) = 1,96

Test Hypothesis:

Null Hypothesis                                  H₀           μ₁  = μ₂

Alternative Hypothesis                      Hₐ            μ₁  ≠ μ₂

The alternative hypothesis tells us that the test is a two-tail test.

z(s)  =  ( μ₁  - μ₂ ) / √ σ₁²/n₁  + σ₂²/n₂

z(s)  = ( 169,9  -163,3 ) / √ (24,8)² /115   +  ( 25,8)²/235

z(s)  =  6,6  / √5,35 + 2,83

z(s)  =  6,6  / 2,86

z(s) = 2,30

Comparing  |z(c)|    and  |z(s)|

z(s) > z(c)

z(s) is in the rejection region we reject H₀     μ₁  = μ₂  and support the claim that at CI 95 % the means of the two groups differs
