This is correct. Indeed, since there are four categories in this problem (the four capacity models 32GB, 64GB, 128GB and 256GB), we need to use row 4 - 1 = 3 in the table. As the image below shows, the critical value that corresponds to a significance level of 0.05 is 7.815....
Read MoreIf the null hypothesis is correct, how many phones (out of 284 phones that were sold) would you expect to be sold from the 32GB, 64GB, 128GB, 256GB models, respectively? In other words, what are the expected frequencies in this case?
71, 71, 71, 71This is correct. Indeed, if the null hypothesis is true (equal demand to all four models) then we would expect the 284 sold phones to be equally divided among the four models. In other words, we would expect that the total sales of each model will be 284/4=71....

Read MoreA 2012 study reported that the opinions of U.S. adults regarding the the issue of abortion has the following distribution:
Legal in all cases | Legal in most cases | Illegal in most cases | Illegal in all cases | Unsure |
|---|---|---|---|---|
.23 | .31 | .23 | .16 | .07 |
700 randomly chosen U.S. adults were recently asked about their opinions regarding abortion and the data showed that:
We have evidence to conclude that the data do not fit the distribution reported by 2012 study.This is correct. Since the p-value is between 0.01 and 0.02, then p-value < 0.05 and therefore we can reject H0 and conclude that the data do not fit the distribution reported by the 2012 study....

Using the chi-square table (linked hereopens a new window), what can you say about the p-value of the test?
0.01 < p-value < 0.02This is correct. Since there are 5 categories in this case (Legal in all cases, Legal in most cases, Illegal in most cases, Illegal in all cases, Unsure), you need to use row 5-1=4 in the table. As the figure below shows, since the test statistic 12.02 falls between the tw...

A company has released its new phone which is available in 4 capacity models: 32GB, 64GB, 128GB, and 256GB. A store has sold 284 phones over the last week: 63 phones of the 32GB model, 73 phones of the 64GB model, 77 of the 128GB model, and 71 of the 256GB model. We will use the chi-square goodness-of-fit test to asses whether the four models’ total sales are significantly different from one another.
