In chapter 9, we discussed Confidence Interval methodology to draw conclusions about the difference in the brain size of the chi
ldren with and without autism. Discuss a different methodology to conclude if there is any significant difference in the average brain size of the children with and without autism.
The two sample t test can be used in the scenario described above, where two independent samples are obtained, we take a certain sample of children with autism and then another sample of children without autism. The number of children chosen for each sample should be random and could be of equal or unequal sizes. The mean and standard deviation of each of sample A and B are deternined and used to perform the analysis to determine if the mean of each sample are equal or not. This test is also called the WELCH T TEST
It would be the negative form of those bumbers and the non-negative form of those numbers. The absolute value applies to negative numbers the same. For example absolute value of -3 is 3.
L=25 If the length is 25 yards then you use 50 yards of fencing for the length, this leaves ten yards for each width of fencing each. 10 yards is 15 yards less than 25 yards showing that this is the correct answer.
