Answer:

d. 0.26

Step-by-step explanation:

We are asked to find the value of the The sine of the complimentary angle to 75°.

Since we know that complementary angles add up-to 90 degrees, so let us find the measure of complementary angle of 75° angle by subtracting 75° from 90°.

\text{Measure of complementary angle}=90^o-75^0

\text{Measure of complementary angle}=15^0

Now let us find the sine of 15 degree angle. Using a calculator we will get,

sin(15^o)=0.258819045103

Upon rounding our answer to nearest hundredth we will get,

sin(15^o)\approx 0.26

Therefore, the sine of complementary angle to 75° is 0.26 and option 'd' is the correct choice.

Several factors influence the size of the F-ratio. For each of the following, indicate whether it would influence the numerator
enyata [817]

Answer:

(a) Increase the differences between the sample means this will increase the Numerator.

(b) Increase the sample variances will increase the denominator.

Step-by-step explanation:  

F Ratio = Variance between treatments/ Variance within treatments.  

Here,  

(a) Increase the differences between the sample means:  

  - Will increase the Numerator and  

  - Size of the F-ratio would increase  

(b) Increase the sample variances:  

 - Will increase the denominator and  

 - Size of the F Ratio would decrease.

A population of size 320 has a proportion equal to .60 for the characteristic of interest. What are the mean and the standard de
tiny-mole [99]

Answer:

The answer is c.) 0.6 and 0.14

Step-by-step explanation:

Given population has a size of 320.

The proportion of population = 0.6

The mean of population, p = 0.6

The mean of sample, \hat{p}= 0.6

Therefore \hat{q}  = 1 - \hat{p} = 1 - 0.6  = 0.4

The sample size  = 12

Therefore the standard deviation of the sample,

s = \sqrt{\frac{\hat{p}(1 - \hat{p})}{n} }  = \sqrt{\frac{0.6 \times 0.4}{12} }  = 0.1414

The mean and the standard deviation for a sample size of 12 are 0.6 and 0.14 respectively.

The answer is c.) 0.6 and 0.14
