Complete Question
A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 12 % chose chocolate pie, and the margin of error was given as plus or minus 5 percentage points.What values do , n, E, and p represent? If the confidence level is 90%, what is the value of ?
Answer:
a
is the sample proportion
is the sample size is
is the margin of error is
represents the proportion of those that did not chose chocolate pie i.e
b
Step-by-step explanation:
Here
is the sample proportion

Generally is the level of significance and it value is mathematically evaluated as
Where is the confidence level which is given in this question as
So
Answer: the diffrence is 2
Step-by-step explanation:
If I ran 5 times last week, the miles covered is
Option C is correct.
Step-by-step explanation:
Miles ran in park each day=
We need to find how much distance you ran 5 times last week.
Miles covered in 1 day =
Miles covered in 5 days =
Miles covered in 5 days =
Miles covered in 5 days =
So, if I ran 5 times last week, the miles covered is
Option C is correct.

For this case we have the following product:
a ^ 4 • a ^ 6
For power properties we have:
"same base add the exponents"
We have then:
a ^ 4 • a ^ 6 = a ^ (4 + 6)
a ^ 4 • a ^ 6 = a ^ 10
Answer:
The product a ^ 4 • a ^ 6 is:
a ^ 10
Answer:
A. Statistic = A numerical measure that describes an aspect of a sample.
B.) Null hypothesis = A claim about a population parameter.
C.) Slope of the least square line = Marginal change in response variable.
D.) Population = All Objects or individual of interest
E.) P - value = Probability, assuming null hypothesis is true, that test statistic will take a value as extreme as observed.
F.) Coefficient of determination = Ratio of explained variation over total variation in y that can be explained by the regression equation using x as the explanatory variable.
G.) Z score = Distance from mean in terms of standard deviation units.
H.) Parameter = A numerical measure that describes an aspect of a population.
I.) Sampling distribution = Probability distribution of a sample statistic
J. Sample = Some individuals or objects of interest
Step-by-step explanation:
Answer is Explanatory
