Answer:
E. 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:
The entire population of Greek and Egyptian mathematicians was already measured by Amara. She can measure the actual difference in the mean. Therefore, she needn't use a confidence interval. It is mostly common for a researcher to be more interested in the difference between means than in the specific values of the means. The difference in sample means is used to compute the difference in population means.
Amara's sample is a random selection of Greek and Egyptian mathematicians. It is a smaller group drawn from the population that has the characteristics of the entire population. The observations and conclusions made against the sample data are attributed to the population. In this case, the entire position is measured.
A t-test is a type of inferential statistic used to determine if there is a significant difference between the means of two groups (Greek and Egyptian mathematicians) which may be related in certain features. It is mostly used when the data sets, like the data set recorded as the outcome from rolling a die 50 times, would follow a normal distribution and may have unknown variances. A t-test is used as a hypothesis testing tool, which allows testing of an assumption applicable to a population. Once the actual difference is known, a confidence interval should not be used.

The "n" and "U" should be drawn as curved lines (I'm drawing using the keys available to me but if this were hand-drawn the graph would be more ~ -curvy/wavy looking)
The Y-axis "Height in Feet": shows the height of their head from the ground in feet as they bounce
The X-axis "Length of Passing Time in Seconds": shows the seconds as they pass while jumping on the pogo stick
The assumption being made: The head isn't starting from 0 feet off the ground so we began the line near the 5-foot mark
Remember to label your x and y axises
the answer is 44 just do 86- 42 and it gives you the answer
Answer:less than 24 °C as soil loses heat relatively faster than water. It will be less than 24 °C as water loses heat relatively faster than soil. It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature. It will be more than 24 °C as it takes relatively longer to change water temperature than soil temperature.
Step-by-step explanation:
less than 24 °C as soil loses heat relatively faster than water. It will be less than 24 °C as water loses heat relatively faster than soil. It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature. It will be more than 24 °C as it takes relatively longer to change water temperature than soil temperature.
Answer:
GLH is congruent to JLK as the quadrilateral is a parallelogram,
KJ = GH OR HJ = GK
GL = LJ OR. HL = LK
triangle JKG = GHJ
triangle HGK = KJH
