Question

find the mean for the given sample data. unless indicated otherwise, round your answer to one more decimal place than is present in the original data values. the amount of time (in hours) that sam studied for an exam on each of the last five days is given below. 1.7 7.7 8.3 1.6 5.1 find the mean study time. (1 point) 4.88 hr 4.96 hr 5.45 hr 24.40 hr

Explanation:

Step1: Sum up the data values

$$1.7 + 7.7+8.3 + 1.6+5.1=24.4$$

Step2: Divide by the number of data values

There are \(n = 5\) data values. The mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), so \(\bar{x}=\frac{24.4}{5}=4.88\)

Answer:

4.88 hr
