Here are the observed frequencies from four categories: 5, 6, 8, 13.
Assume we want to use a 0.05 significance level to test the claim that the four categories are all equally likely. (Goodness of fit test)
- What is the null hypothesis?
- What are the expected frequency for each of the four categories?
- What is the value of the test statistic?
- What is the critical value?
- What do you conclude about the given claim?

ANSWER:
From the given information,
By using calculator,
The required correct answers are,
A. Null hypothesis is,
Ho: Four categories are equally likely.
B. Expected value= 32/4 = 8
C. Test statistic= 4.75
D. Critical value= 7.815
E. Failed to reject null hypothesis.
Hence, We can conclude that four categories are all equally likely.

The null hypothesis for the goodness-of-fit test is that the
proportion of all elements of the population that belong to each of
the four categories is the same. What is the expected frequency for
the second category?

Over the past four years, a stock produced returns of 13, 6, -5,
and 18 percent, respectively.
What is the standard deviation of these returns? What would be the
standard deviation of these returns if they were exactly twice the
return shown for each year? please show your work.
