According to the national association of realtors, it took an average of three weeks to sell a home in 2017. suppose data for the sale of 39 randomly selected homes sold in greene county, ohio, in 2017 showed a sample mean of 3.6 weeks with a sample standard deviation of 2 weeks. conduct a hypothesis test to determine whether the number of weeks until a house sold in greene county differed from the national average in 2017. useα = 0.05for the level of significance, and state your conclusion.(a)state the null and alternative hypothesis. (enter ! = for ≠ as needed.)h0: : )find the value of the test statistic. (round your answer to three decimal places.)find the p-value. (round your answer to four decimal places.)p-value =

1.8732, 0.068

Step-by-step explanation:

Given that according to the National Association of Realtors, it took an average of three weeks to sell a home in 2017.

Sample size n = 39

a)

Std error of sample =

(Two tailed test at 5% significance level)

Mean difference = 0.6

Since population std deviation is not known, t test to be used.

b) Test statistic t = mean diff/std error =

df = 38

c) p value = 0.068

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

5.7622

step-by-step explanation:

the ten thousandths place is the 2. you round it up if, that number in whatever place is 5 or higher.
