Explanation

The null hypothesis is H0. It's a declaration that there's no difference between sample means or proportions, or between a sample mean or proportion and the population mean or proportion. To put it another way, the difference is zero.

The alternative hypothesis is Hα: It's a population claim that goes against the null hypothesis and what we conclude when we reject H0.

We conclude that the passenger's choice of ticket class is unaffected by the distance they must travel, as defined by the null hypothesis. We conclude that the passenger's choice of ticket class is influenced by the distance they must go, as defined by the definition of alternate hypothesis.

The standard deviation of heights for students in a school is 0.81. A random sample of 50students is taken, and the standard deviation of heights of the sample is 0.96. A researcher in charge of the study believes the standard deviation of heights for the school is greater than 0.81.

What type of test should be used?

The Insurance Institute for Highway Safety collects safety information about all types of cars every year, and publishes a report of Top Safety Picks among all cars, makes, and models. Table 11.58 presents the number of Top Safety Picks in six-car categories for the two years 2009 and 2013. Analyze the table data to conclude whether the distribution of cars that earned the Top Safety Picks safety award has remained the same between 2009 and 2013. Derive your results at the 5%
