Explanation

H0:The null hypothesis is as follows: It's a declaration that there's no difference between mean differences or percentage, or between a sample mean or proportion and the community mean or proportion. To put it another way, the discrepancy is zero.

Ha:The other alternative is: It's a demographic claim that goes against the assumptions and what we conclude when we reject H0.

We conclude that the private doctor and the hospital doctor have the same working hour distributed based on the concept of null hypothesis.

We infer that private doctors and hospital doctors do not share the same working hour allocation, based on the concept of alternate hypothesis.

A sample of 212commercial businesses was surveyed for recycling one commodity; a commodity here means any one type of recyclable material such as plastic or aluminum. Table 11.41shows the business categories in the survey, the sample size of each category, and the number of businesses in each category that recycle one commodity. Based on the study, on average half of the businesses were expected to be recycling one commodity. As a result, the last column shows the expected number of businesses in each category that recycle one commodity. At the 5% significance level, perform a hypothesis test to determine if the observed number of businesses that recycle one commodity follows the uniform distribution of the expected values.
