A frequency table is a table with the frequency of each actual value in the data set.

Approach:

From the given table the number of students with a score of 10 is 1, so the frequency of score 10 is 1, similarly the number of students with a score of 40 is 1, so the frequency of score 40 is 1 similarly frequencies for rest of scores can be computed.

The frequency table for the Chem 103 test is given by,

Score Frequency

A bar graph is a graph with bars (column) representing each of the actual values in the data set. The height of each column represents the frequency of the value in the data set.

Approach:

From the given table the number of students with a score of 0 is 0, so the frequency of score 0 is 0, similarly the number of students with a score of 10 is 1, so the frequency of score 10 is 1 similarly frequencies for rest of scores can be computed.

The frequency table for the Chem 103 test is given by,

Score Frequency
0 0
10 1
20 0
30 0
40 1
50 3
60 7
70 6
80 5
90 0
100 2

Place the scores along horizontal axis and the frequencies along vertical axis to construct bar graph. The bar graph of the frequency table is given below.

Module Code: MATH380202 1. (a) Define the terms "strongly stationary" and "weakly stationary". Let {X} be a stochastic process defined for all t € Z. Assuming that {X+} is weakly stationary, define the autocorrelation function (acf) Pk, for lag k. What conditions must a process {X+) satisfy for it to be white noise? (b) Let N(0, 1) for t€ Z, with the {+} being mutually independent. Which of the following processes {X+} are weakly stationary for t> 0? Briefly justify your answers. i. Xt for all > 0. ii. Xo~N(0,) and X₁ = 2X+-1+ &t for t > 0. (c) Provide an expression for estimating the autocovariance function for a sample X1,..., X believed to be from a weakly stationary process. How is the autocor- relation function Pk then estimated, and a correlogram (or acf plot) constructed?
