1. The following data shows the yearly income distribution of a sample of 200 employees at MNM, Inc. Yearly Income ($1000s) 20-24 MSTS000 ASSIGNMENT 1 a. b. d. e. 25-29 30-34 35-39 40-44 8. Number of Employees 2 48 60 80 10 TOTAL MARKS: 30 DATE: 26/02/2024 What percentage of employees has yearly incomes of more than $35,000? (2) Is the figure (percentage) that you computed in Part an example of statistical inference? If no, what kind of statistics does it represent? (2) Based on this sample, the president of the company said that "45% of all our employees' yearly incomes are over $35,000." The president's statement represents what kind of statistics? (1) With the statement made in Part c, can we be assured that more than 45% of all employees' yearly incomes are at least $35,000? Explain. (2) (2) (1) (1) What percentage of employees of the sample has yearly incomes of $29,000 or less? How many variables are presented in the above data set? The above data set represents the results of how many observations?

Question 4The researcher wishes to use graphical descriptive methods to present summaries of the data on each of the two variables: hours worked per week and yearly income, as stored in file HOURSWORKED.jpga) The number of observations (n) is 65 individuals. The researcher suggests using 7 class intervals to construct a histogram for each variable. Explain how the researcher would have decided on the number of class intervals (K) as 7. b) The researcher suggests using class intervals as 10 < X ≤ 15, 15 < X ≤ 20, …, 40 < X ≤ 45 for the hours per week variable and class intervals 40 < X ≤ 45, 45 < X ≤ 50, ..., 70 < X ≤ 75 for the yearly income variable. Explain how the researcher would have decided the width of the above class intervals (or class width). c) Draw and display a histogram for each of the two variables using appropriate BIN values from part (b) and comment on the shape of the two distributions.

In Table L-1, the total value of imports of Indonesian goods and services from China for the 2010-2019 period is reported on a quarterly basis. With this data you are asked to analyze it with the Trend model and Seasonal Index. Question: a. Calculate a moving average with the average period length of 4 or MA (4) [why four?] And put the results in a column. Beware of selecting the rows to place the average result. b. Calculate the moving average with the length of the average period is 2 from the data in column MA (4) and the result is given the symbol MA (2x4) and the result is placed in a column. Beware of selecting the rows to place the average result. c. Calculate the ratio to the Moving Average (Y / MA (2x4)) and place it in a new column! d. Calculate a seasonal index and interpret the results! e. Create a Deseasonalized data series and place it in a new column! f. Plot the Dessasonalized data series and read the long-term movement patterns of data! Remember that understanding of…
