Answer:
3/4
Step-by-step explanation:
Use the data given below to answer the following questions 68,63,67,66,65,87,69,61,86,82,28, a. What is the outlier of the data?
Lady_Fox [76]
The outlier is 28 because there is a big gap between 28 and 61
to find the mean add all the numbers together then
divide the number of values added
First you find the percent of 12. 8% of 12 is 0.96. you must add that to 12 and you get $12.98
Answer:
x = 5
Step-by-step explanation:
The difference between a hour of amounts is 8
therefore, 5 hours for 37 amount
Answer:
The 95% confidence interval for the difference in mean profile height and mean actual height of online daters is between 0.27 and 0.87 inches.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 30 - 1 = 29
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 29 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.0452
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 0.57 - 0.3 = 0.27 inches.
The upper end of the interval is the sample mean added to M. So it is 0.57 + 0.3 = 0.87 inches.
The 95% confidence interval for the difference in mean profile height and mean actual height of online daters is between 0.27 and 0.87 inches.
