A census collected data from a random sample of 121 people living in star city. The sample average of the distance people travel to teach their workplaces is () is 20.35 km and the standard deviation is (s_y) is 7.48 km.

The standard error of the sample average of the distance people travel to reach their workplaces is ? km (rounded to nearest two decimal points)

Let _y denote the mean of the distance all the people in star city travel to reach their workplaces

The p-value of the test H₀: _y = 22km vs. H₁ : _y 22km is ? (rounded to nearest two decimal points)

Also the p-value suggests that at the 5% significance level, we fail to reject or reject the hypothesis that the mean distance people travel to reach their workplace in star city is 22km?
