Answer:
16, 60, 20
Step-by-step explanation:
This is an equilateral triangle and since the LN is 16, LM must be as well.
The second, again is equilateral, so the angles must all be 60 degrees.
The last question is equilateral so all angles are equal to 60, and 60/3 is equal to 20.
Answer: 709
Step-by-step explanation:
The formulas we use to find the required sample size :-
1. 
, where 
= population standard deviation,
E = Margin of error .
z* = Critical value
2. 
, where p= prior estimate of population proportion.
3. If prior estimate of population proportion is unavailable , then we take p= 0.5 and the formula becomes
Given : Margin of error : E= 3% =0.03
Critical value for 95% confidence interval = z*= 1.96
A study conducted several years ago revealed that the percent of junior executives leaving within three years was 21%.
i.e. p=0.21
Then by formula 2., the required sample size will be :
[Round to the next integer.]
Hence, the required sample size of junior executives should be studied = 709
Answer:
first one im pretty sure
Step-by-step explanation:
In anova, by dividing the mean square between groups by the mean square within groups, a(n) Analysis of variance statistic is computed.
What is Analysis of variance ?
- With the help of the statistical analysis approach known as ANOVA, apparent aggregate variability within a data set is explained by separating systematic components from random factors.
- Systematic influences, but not random ones, statistically affect the data set that is being presented.
What are some instances where ANOVA has been applied?
- An ANOVA demonstrates the link between the dependent variable and the level of the independent variable.
- For illustration: In order to determine whether there is a difference in the number of hours of sleep each night as your independent variable, you divide the groups into low, medium, and high social media use categories.
