Answer:
(C) Because the p-value is greater than α, we fail to reject the null hypothesis and cannot conclude that the average age of PlayStation users is different from the average age of Xbox users.
Step-by-step explanation:
The t-statistic for difference of mean is given by,
[tex]t=\frac{\bar{x_{1}}-\bar{x_{2}}}{\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}}}}[/tex]
Using this formula, we get, t = 1.5342
Thus, p-value = 0.1322 with 64 degree of freedom.
and α = 0.10
Since, the p-value is greater than alpha (p > .05), then we fail to reject the null hypothesis, and we say that the result is statistically non-significant.
