Seventy-three UPS drivers and 80 Federal Express drivers from the Los Angeles area were given surveys asking about their driving habits and experiences. The researchers found that seven UPS drivers and 17 Federal Express drivers from the sample had received parking tickets during that week. The researcher's null and alternative hypotheses are: Ho: P = P2 H₁: P P2 P₁ = UPS, P₂ = Federal Express, and a = 0.05 Of the following, which shows the correct test statistic, P-value, and conclusion? Oz= -1.981; P-value = 0.0476. There is sufficient evidence to reject the null hypothesis that the proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers who receive tickets. Oz -1.981; P-value = 0.0238. There is sufficient evidence to reject the null hypothesis that the proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers who receive tickets. Oz -2.436; P-value = 0.0148. There is sufficient evidence to reject the null hypothesis that the proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers who receive tickets. Oz-2.436; P-value = 0.0074. There is sufficient evidence to reject the null hypothesis that the proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers who receive tickets.

Seventy three UPS
Transcribed Image Text:Seventy-three UPS drivers and 80 Federal Express drivers from the Los Angeles area were
given surveys asking about their driving habits and experiences. The researchers found that
seven UPS drivers and 17 Federal Express drivers from the sample had received parking
tickets during that week. The researcher's null and alternative hypotheses are:
Ho: A = P₂
H₁ AP₂
A = UPS, 7₂ = Federal Express, and a = 0.05
Of the following, which shows the correct test statistic, P-value, and conclusion?
Oz=-1.981; P-value = 0.0476. There is sufficient evidence to reject the null hypothesis that the
proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers
who receive tickets.
Oz -1.981; P-value = 0.0238. There is sufficient evidence to reject the null hypothesis that the
proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers
who receive tickets.
Oz--2436; P-value = 0.0148. There is sufficient evidence to reject the null hypothesis that the
proportion of UPS drivers who receive parking tickets equals the proportion of Federal Express drivers
who receive tickets.
== -2436; P-value = 0.0074. There is sufficient evidence to reject the null hypothesis that the
proportion of UPS drivers who recente parking tickets equals the proportion of Federal Express drivers
who receive tickets.
