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
Homework Answers
We have for given example,
Population proportion value is =0.2
x=102
n=600
Estimate for sample proportion =0.17
P value =0.967.............for right tailed test by using Z table or Excel =1-NORMSDIST(-1.84)
| A. 0.967 |

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%...

The highway department is testing two types of reflecting paint for concrete bridge end pillars. The two kinds of paint are alike in every respect except that one is orange and the other is yellow. The orange paint is applied to 12 bridges, and the yellow paint is applied to 12 bridges. After a period of 1 year, reflectometer readings were made on all these bridge end pillars. (A higher reading means better visibility.) For the orange paint, the mean...

Based on information from a previous study, r = 34 people out of a random sample of n = 101 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 101 adult Americans who did attend college, '2 = 47 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend...

Carboxyhemoglobin is formed when hemoglobin is exposed to carbon monoxide. Heavy smokers tend to have a high percentage of carboxyhemoglobin in their blood.† Let x be a random variable representing percentage of carboxyhemoglobin in the blood. For a person who is a regular heavy smoker, x has a distribution that is approximately normal. A random sample of n = 12 blood tests given to a heavy smoker gave the following results (percent carboxyhemoglobin in the blood). Note: For degrees of...
