Instruction: when you do the frequency distribution use 10 classes. You can attach a pdf or word document file. This is another similar question in determining normality (section 6.2). Each part worth 4 points.


Question:


The numbers of branches of the 50 top banks are shown below:   


67 84 80 77 97 59 62 37 33 42 36 54 18 12 19 33 49 24 25 22 24 29 9 21   


21 24 31 17 15 21 13 19 19 22 22 30 41 22 18 20 26 33 14 14 16 22 26 10 16 24.


construct a frequency distribution for the data

construct a histogram for the data

describe the shape of the histogram

check for outliers

calculate the Pearson Coefficient of Skewness

What is your conclusion? Is the data normal?

Please show all your steps.

What is a t-distribution? Compare the t-distribution and the standard normal distribution. When do you use the t-distribution? The height of US women is normally distributed. A sample of 25 women shows an average hight of 160cm with a standard deviation of 5cm. Use t distribution to find the probability that the average height of randomly selected 25 women is greater than 172cm.

Q.2. The frequency distribution is a table that divides the data values into classes and shows the number of observed values that fall into each class. By converting data to a frequency distribution, we gain a perspective that helps us see the forest instead of the individual trees. Hence, the data is presented using charts and figures is widely followed method in descriptive statistics. In this connection, you are required to explain the meaning of histogram, frequency polygon and presents...
