Answer:
Mode
Step-by-step explanation:
Mean:
Before replacing = 464/8 = 58
After replacing 42 with 98 = 520/8 = 65
Mode:
Before replacing = 42
After replacing 42 with 98 = 98
Median:
25, 42 , 42 , 47, 55 , 59, 96,98
Before replacing = 47+55/2 = 51
25, 42 , 47, 55 , 59, 96,98 , 98
After replacing 42 with 98 = 55+59/2 = 114/2 = 57
Answer:
AC = 55°
Step-by-step explanation:
In this geometry, arcs AC and BD have the same measure. The sum of the parts of arc CD will total the measure of CD.
AC + AB + BD = CD
2AC +80 = 170
AC = 110/2 = 55
The measure of arc AC is 55°.
Answer: 70,000
Step-by-step explanation:
Answer:
1. The null hypothesis is that there is no difference between the population means (in other words, there is no treatment effect).
2. The<u> alternative hypothesis</u> is that at least one of the population means is different from another (in other words, there is an effect Of at least one Of the treatments).
Step-by-step explanation:
In a statistical analysis, the statistician shares his participants into several groups and administers treatments to them. After administering the treatment, he might want to compare the values obtained to see if there is a difference. If he accepts the null hypothesis as true, that means that there was no difference between the population means. This can also be taken to mean that the result had no difference among the groups.
But if the alternative hypothesis was true, that means that the population means were not all equal and so, there was an effect from the treatment administered.
