The following table contains observed frequencies for a sample of 200.
| Row Variable |
Column Variable | ||
|---|---|---|---|
| A | B | C | |
| P | 18 | 42 | 48 |
| Q | 32 | 28 | 32 |
Test for independence of the row and column variables using
α = 0.05.
State the null and alternative hypotheses.
H0: Variable P is independent of variable
Q.
Ha: Variable P is not independent of variable
Q.H0: The column variable is independent of the
row variable.
Ha: The column variable is not independent of
the row variable. H0:
The column variable is not independent of the row variable.
Ha: The column variable is independent of the
row variable.H0: Variable P is not independent
of variable Q.
Ha: Variable P is independent of variable
Q.
Find the value of the test statistic. (Round your answer to three decimal places.)
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
Reject H0. We conclude that the column and row variables are independent.Do not reject H0. We cannot conclude that the column and row variables are independent. Do not reject H0. We cannot conclude that there is an association between the column variable and the row variable.Reject H0. We conclude that there is an association between the column variable and the row variable.

A report states that adults 18- to 24- years-old send and
receive 128 texts every day. Suppose we take a sample of 25- to 34-
year-olds to see if their mean number of daily texts differs from
the mean for 18- to 24- year-olds.

State the null and alternative hypotheses we should use to test
whether the population mean daily number of texts for...

A research center has conducted extensive research on social
media usage. One finding was that 71% of adults aged 18 to 24 use
Snapchat. Another finding was that 48% of those aged 18 to 24 use
Twitter. Assume the sample size associated with both findings is
400.
