Complete parts (a) through (d) for the sampling distribution of the sample mean shown in the accompanying graph. Click the icon to view the graph. (a) What is the value of u? The value of u; is 700 (b) What is the value of o;? The value of o; is 20. (c) If the sample size is n= 9, what is likely true about the shape of the population? O A. The shape of the population is skewed right. B. The shape of the population is approximately normal. OC. The shape of the population is skewed left. O D. The shape of the population cannot be determined. (d) If the sample size is n= 9, what is the standard deviation of the population from which the sample was drawn? The standard deviation of the population from which the sample was drawn is 680 700 720 The distribution is normal. The locations of the peak and inflection points are shown.

describe the steps you would take to construct a frequency distribution

In the frequency distribution below, the first column (class limits) gives the age ranges (in years) of people who participate in a survey. The second column gives the frequency for each age range. a. Determine the class width. If needed, you can use the space below the table. b. Complete the rest of the frequency distribution. For the relative frequency column, round your answers to 2 decimal places. Class Limits Frequency Class Boundaries Class Midpoints Relative Frequency Cumulative Frequency 18-26 16         27-35 24         36-44 38         45-53 34         54-62 26         63-71 12         Total                          150

Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below. Compute the relative and cumulative relative frequencies and use a line chart to construct an ogive.   Complete the frequency distribution for the months as a​ customer, and compute the relative and cumulative relative frequencies. ​(Type integers or decimals rounded to three decimal places as​ needed.)
