Answer:
The median is 72
Step-by-step explanation:
The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.
In this question:
Scores: 86, 67, 62, 82, 64 and 77
Sorted: 62, 64, 67, 77, 82, 86
Middle elements: 67 and 77
Median: (67 + 77)/2 = 72
The median is 72
3.60
t = r√n − 2/1 − √r2
= 0.6√25 − 2/√1 − 0.62
= 3.5969 t or about 3.60 rounded to two decimal places.
Hypothesis Testing:
Hypothesis testing is a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or a population probability distribution. First, a tentative assumption is made about the parameter or distribution. This assumption is called the null hypothesis and is denoted by H0.
