Test whether departure time(DPETTIME) differs depending on intrusion condition. Use the 0.05 significance level and a two-tailed test. Report the appropriate test statistic, df, and p-value for the test.Include thestatistical outputthat shows these values. Interpret the results in substantive terms. That is, does departure time differ significantly by intrusion condition? If so, which group has a longer departure time?

Question

Test whether departure time(DPETTIME) differs depending on intrusion condition. Use the 0.05 significance level and a two-tailed test.

Report the appropriate test statistic, df, and p-value for the test.Include thestatistical outputthat shows these values.

Interpret the results in substantive terms. That is, does departure time differ significantly by intrusion condition? If so, which group has a longer departure time?

Use the sample data to determine the mean and standard deviation for two intrusion condition.

$\begin{array}{rcl} \bar{x} & = & \frac{\sum x}{n_{1}} \\ = & \frac{3986.06}{124} \\ = & 32.1456 \end{array}$

$\begin{array}{rcl} s_{1} & = & \sqrt{\frac{\sum {(x - \bar{x})}^{2}}{(n_{1} - 1)}} \\ = & \sqrt{\frac{17419.25365}{(124 - 1)}} \\ = & 11.9004 \end{array}$

$\begin{array}{rcl} \bar{y} & = & \frac{\sum y}{n_{2}} \\ = & \frac{2966.34}{76} \\ = & 39.0308 \end{array}$

$\begin{array}{rcl} s_{2} & = & \sqrt{\frac{\sum {(y - \bar{y})}^{2}}{(n_{2} - 1)}} \\ = & \sqrt{\frac{24968.25495}{(76 - 1)}} \\ = & 18.2458 \end{array}$
