A car dealership looked back at the previous year sales records last year the dealership sold 422 vehicles that mean sale price

was 24,500 with a standard deviation of 12,875 dealership Also discovered that the distribution of the sale price is skewed to the right at the dealership we’re to select repeated random samples of 40 vehicles from the population of a vehicle sold last year and calculate the average sale price for each sample of 40 which of the following gives the correct mean and standard deviation of the sampling distribution of the sample mean

Answer: mean= 24,500 stan dev.= \frac{12875}{\sqrt{40}}

Explanation: Because the sample size is large (n = 40 > 30) the sampling distribution of the sample mean sales price is approximately normal.

Answer:

(A) Mean = $24,500, Standard deviation = 12,875/ √40

​  

Explanation:

Because the sample size is large (n = 40 > 30) the sampling distribution of the sample mean sales price is approximately normal. The mean is

μx =μ=24,500 and the standard deviation is the standard deviation divided the square root of n

Identify ways party leaders can influence members of their party in Congress
patriot [66]
The Speaker decides which bills will be assigned to which committees. This is one way he or she can use party leadership to influence members of their party in Congress. If a wayward member is sponsoring a bill, the Speaker may assign that bill to a committee where the bill is likely to get an unfavorable reception and be killed. Conversely, the Speaker can assign the bill to a safe committee where the bill will receive a favorable reception in exchange for the sponsor’s party loyalty.

The weight Lucy lost with respect to number of weeks was recorded for six weeks. The correlation coefficient was calculated to b
Aleonysh [2.5K]

Answer: There is a weak, positive correlation between the weight Lucy lost and the number of weeks.

Explanation:

The correlation coefficient is used to measure the relationship between two variables in terms of how they move in relation to one another.

If two variables are said to have a positive correlation, it means that they increase at the same time and decrease at the same time for example, there is a positive correlation between the amount of food a family buys and how much money they have because the more money they have, the more food they buy.

Negative correlations are the reverse for instance Ice cream sales and cold temperatures. The colder it is, the less people buy ice cream.

The Correlation coefficient ranges from -1 to +1 with +1 (-1) meaning that the variables are perfectly positively(negatively) correlated. The closer the value is to 0, the weaker the correlation.

Generally, for a correlation coefficient between the numbers 0 and +0.3, there is a weak positive correlation.

With a correlation coefficient of 0.0502, there is therefore a weak, positive correlation between the weight Lucy lost and the number of weeks.

The easiest way to find such limits, where there is a numerator and a denominator is to apply <span><span>Hospital's Rule.
1st find the derivative of the numerator and the derivative of the denominator, if it still gives an indeterminate value, find the second derivative of N and D

3) lim sin(2x)/x when x →0
 Derivative sin2x → 2cos2x
 Derivative x→ 1
 2cos2x/1 when x→0 , 2cos2x → 2
 and lim sin(2x)/x when x →0 is 2

4) lim(sinx)/(2x²-x)

→cosx/(2x-1) when x →0 cosx/(2x-1) = -1
and lim(sinx)/(2x²-x) when x →0 is -1

and so on and so forth. Try to continue following the same principle
