You first have to see if they have the same common denominators. If they do then the operation as in addition you add the numerator and denominator together and she if it can be reduced into a smaller number
Answer: The population proportion is between 0.34 and 0.46 .
Step-by-step explanation:
Interpretation of 95% confidence interval : A person can be about 95% confident that the true population parameter lies in the interval.
A confidence interval is constructed for an unknown population proportion, p. A sample is collected, and the 95% confidence interval is calculated to be 0.40 ± 0.06.
i.e. Lower limit = 
Upper limit = 
i.e. 95% confidence interval = (0.34, 0.46)
i.e. A person can be about 95% confident that the true population proportion (p) lies in the interval (0.34, 0.46).
⇒ It is most accurate to say that there is approximately 95% confidence in the assertion that:
The population proportion is between 0.34 and 0.46 .
Answer:
Variance is the difference between a Budgeted Amount and the Actual Amount. In terms of expenses, if the Budgeted amount is more than the Actual amount, the variance is Favorable because less was spent than was supposed to be spent.
The reverse is true.
Variance = Budgeted Amount - Actual amount
= 255 - 225
= $30
Percentage = Variance / Budgeted amount
= 30/255
= 11.76%
The variance is <u>FAVORABLE</u> because the actual amount was less than the budgeted amount.
