Refer to the accompanying data set and use the 25 home voltage measurements to construct a frequency distribution with five classes. Begin with a lower class limit of 123.5 volts, and use a class width of 0.2 volt. Does the result appear to have a normal distribution? Why or why not? E Click the icon to view the data. Complete the frequency distribution below. Frequency Voltage (volts) 123.5 - 123.6 5 123.7 - 123.8 123.9 - 124.0 4 124.1 - 124.2 6 124.3 - 124.4 (Type integers or decimals rounded to the nearest tenth as needed.) Does the result appear to have normal distribution? Why or why not? O A. No, because the frequencies are not equal across the voltage classes. O B. No, because the frequencies are roughly equal across the voltage classes. OC. Yes, because the frequencies start low, reach a maximum, then become low again, and are roughly symmetric about the maximum frequency. O D. No, because the frequencies are randomly distributed. O E. Yes, because the frequencies are roughly equal across the voltage classes.

The following histogram shows the exam scores for the pre algebra class. Use this histogram to answer the questions. Find the class width for this histogram.
Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2…
A recent Nielsen analysis found that the typical U.S. smartphone user is spending an average of 220 minutes per day using apps. We speculate that the average time spent using apps for Generation X smartphone users (aged 41-56 years) is less than the national average. The hypotheses are Ho: H = 220 minutes versus Ha: µ < 220 minutes. Summary results from R are provided. Summary Statistics Std. Dev (s) Mean Sample Size (n) 205 minutes 63.25 minutes 31
