5. The female students in an undergraduate engineering core course at UH self-reported their heights to the nearest inch. The data is as follows. 62 64 61 67 65 68 61 65 60 65 64 63 59 68 64 66 68 69 65 67 62 66 68 67 66 65 69 65 69 65 67 67 65 63 64 67 65 First construct the frequency distribution Table like Table 6-4 on Page 213 of textbook where you only need to specify the classes/bins, frequency info. Then using the table to create the histogram; here let the height of rectangle (for each bin) equal to the frequency instead of relative frequency in your histogram even though you can also set the height as the relative frequency. Hint: create the frequency distribution table by hand, but you can create the histogram in Excel and insert the result as a figure.
The included table presents the percentage of each state’s residents who were living in poverty in 2002. The data includes a data value for the District of Columbia so there are 51 data values.

A graduate-level computer science course only gives the grades of A, B, or C. The department has determined that there should be 40% A's given, 40% B's given and 20% C's given as final grades for the course. For the spring 2021 semester, 200 students took the course and 100 students received A's, 50 students received B's and 50 students received C's, so those are my observed frequencies. We want to do a Chi-square Multinomial Goodness of Fit test to see if our grading guidelines match up with what is actually happening. What is the expected frequency for the grade of B category? Round your answer to the tenths position.
