Answer:
The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.
Step-by-step explanation:
A student working on a report about mathematicians decides to find the 98% confidence interval for the difference in mean age at the time of math discovery for Greek mathematicians versus Egyptian mathematicians. The student finds the ages at the time of math discovery for members of both groups, which include all Greek and Egyptian mathematicians, and uses a calculator to determine the 98% confidence interval based on the t distribution, <u>the entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.</u> There is no as such explanation of this scenario, its just the answer mentioned above.
Answer:
5j-15-2j+2= 3j-13
Step-by-step explanation:
5 times j
5 times 3
minus the ones with the letters
then the ones without
and u get the answer
hope this helps!
The price would be 13$ I believe
Answer:
It should be x=11 instead of x=-11, so he is not correct because he made a sign error.
Step-by-step explanation:
I took the test
Answer:
Mean = Sum of all values / number of values.
Mean is usually known as the best measure of central tendency because it takes all values into account. However, it is easily affected by any extreme value or outlier. The Mean can only be defined on interval and ratio level of measurement
. In simpler terms: "The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers."
Median is the mid point of data when it is arranged in order. It is typically when the data set has extreme values or is skewed in some direction. The median is defined on ordinal, interval and ratio level of measurement
. In simpler terms: "The "median" is the "middle" value in the list of numbers.
"
Mode is the most frequently occurring point in data. It is best for nominal data set in which both median and mode are undefined. The mode is defined on nominal, ordinal, interval and ratio level of measurement. In simpler terms: "The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list."
Hope this helps!
