We believe that the proportion of vehicles crossing a bridge which are heavy goods vehicles (HGVs) is at most 20%. We count 600 vehicles on a given day, and find that 102 are HGVs. The p-value for the hypothesis test is approximately: A. 0.967 B. 0.033 C. 0.066 D. 0.975

Suppose the number of vehicles crossing a bridge each day from 8am to 9am is meant to have a mean value 1500. The engineer counts the number of vehicles crossing the bridge for 25 days. The sample mean from the 25 observations is 1585, and the sample standard deviation is 162. Conduct a hypothesis test assuming an unknown standard deviation, to determine if the true mean is 1500 cars per day or not. Use α=0.05.

A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.73, but given the number of people you've talked to about this same issue, you believe it is different from 0.73. The hypotheses for this test are Null Hypothesis: p = 0.73, Alternative Hypothesis: p ≠ 0.73. If you randomly sample 21 people and 12 of them believe that global warming is a serious issue, what is your test statistic and...

A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.55, but given the number of people you've talked to about this same issue, you believe it is different from 0.55. The hypotheses for this test are Null Hypothesis: p = 0.55, Alternative Hypothesis: p ≠ 0.55. You take a random sample and perform a hypothesis test, getting a p-value of 0.0165. What is the appropriate conclusion? Conclude at the 5%...

A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.78, but given the number of people you've talked to about this same issue, you believe it is greater than 0.78. The hypotheses for this test are Null Hypothesis: p ≤ 0.78, Alternative Hypothesis: p > 0.78.

A small one lane bridge is susceptible to damages from heavy trucks. The bridge has room for only two trucks at most. You will investigate event of possible damage (D) to the bridge when two trucks are driving over bridge simultaneously. A truck weighing station was set near the bridge to estimate the chances of having overloaded trucks. Around 5% of the trucks were estimated to be overloaded ( i.e. above legal limit). The overloading of trucks can be considered...

We will analyze the difference in the fuel efficiency of two new brands of hybrid vehicles. The standard deviations of these two populations are unknown, but the engineers from these companies believe that they are equal. A sample of 38 hybrid vehicles produced by Forde Motors had a mean of 70.3 MPG and standard deviation of 1.6 MPG, and a sample of 33 hybrid vehicles produced by GeM motors had a mean of 69.7 MPG and standard deviation of 4.9 MPG....
