What are the factors of 14 and 7?

The CEO of a software company is committed to expanding the proportion of highly qualified women in the organization’s staff of

pishuonlain [190]

Answer:

Null Hypothesis, $H_0$ : p $\geq$ 45%

Alternate Hypothesis, $H_A$ : p < 45%

Step-by-step explanation:

We are given that the proportion of women in similar sales positions across the country in 2004 is less than 45%.

The collected random sample of size 50 showed that only 18 were women.

Let p = proportion of women in similar sales positions across the country in 2004

So, Null Hypothesis, $H_0$ : p $\geq$ 45%

Alternate Hypothesis, $H_A$ : p < 45%

Here, null hypothesis states that the proportion of women in similar sales positions across the country in 2004 is more than or equal to 45%.

On the other hand, alternate hypothesis states that the proportion of women in similar sales positions across the country in 2004 is less than 45%.

The test statistics that would be used here is One-sample z proportion test statistics, i.e;

T.S. = $\frac{\hat p -p}{\sqrt{\frac{\hta p(1-\hat p)}{n} } }$ ~ N(0,1)

Hence, the above hypothesis is appropriate for the given situation.

3. A researcher randomly selects a sample of 61 former student leaders from a list of graduates of UNCG who had participated in

Sophie [7]

Answer:

not statistically significant at ∝ = 0.05

Step-by-step explanation:

Sample size( n ) = 61

Average for student leader graduates to finish degree ( x') = 4.97 years

std = 1.23

Average for student body = 4.56 years

Determine if the difference between the student leaders and the entire student population is statistically significant at alpha

H0( null hypothesis ) : u = 4.56

Ha : u ≠ 4.56

using test statistic

test statistic ; t = ( x' - u ) / std√ n

= ( 4.97 - 4.56 ) / 1.23 √ 61

= 2.60

let ∝ = 0.05 , critical value = -2.60 + 2.60

Hence we wont fail to accept H0

This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05

D. 240 in. 2. What is the surface area of this rectangular pyramid in

a_sh-v [17]

Surface area of a rectangular pyramid = A + 1/2 p s

Where:

A = area of the base

p = perimeter of the base

s= salnt height = 5 in

A = Area of a rectangle = length x width = 8 x 4 = 32 in2

Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2

SA = 32 + 1/2 * 24 * 5 = 92 in2

What is the answer to this problem 3z+4=34

finlep [7]

Solve for z

3z+4=34

Subtract 4 from both sides.

= 3z=30

Divide both sides by 3

z=10

Hope I helped! :D
