How do you interpret this statement? do you accept the null hypothesis or not?

The records of a random sample of 25 Amazon employees in a large city showed that the average years these employees had worked for the Amazon was ?̅= 4 years. Assume that we know that the population distribution of years Amazon employees have spent with the company is approximately Normal, with standard deviation ? = 1.3 years. Assume all conditions have been met. Construct and interpret a 99% confidence interval for the true mean years the population of Amazon employees have spent with the company.

When completing a hypothesis test you are comparing the two population means. How do you write the null hypothesis? Explain how to determine, in detail, which distribution to use. Assume both distributions are normal or both n's are at least 30. When completing a hypothesis test you are comparing the two population proportions. How do you write the null hypothesis? In order to complete hypothesis test for two population proportions, what requirements need to be met?

A simple random sample of 100 postal employees is used to test if the average time postal employees have worked for the postal service has changed from the value of 7.5 years recorded 20 years ago. The sample mean was x¯ = 7 years with a standard deviation of s = 2 years. Assume the distribution of the time the employees have worked for the postal service is approximately Normal. The hypotheses being tested are H0 : µ = 7.5,...

A study is made of residents in Phoenix and its suburbs concerning the proportion of residents who subscribe to Sporting News. A random sample of n1 = 90 urban residents showed that r1 = 10 subscribed, and a random sample of n2 = 99 suburban residents showed that r2 = 18 subscribed. Does this indicate that a higher proportion of suburban residents subscribe to Sporting News? Use a 5% level of significance. What are we testing in this problem? single...

REM (rapid eye movement) sleep is sleep during which most dreams occur. Each night a person has both REM and non-REM sleep. However, it is thought that children have more REM sleep than adults†. Assume that REM sleep time is normally distributed for both children and adults. A random sample of n1 = 9 children (9 years old) showed that they had an average REM sleep time of x1 = 2.9 hours per night. From previous studies, it is known...

From public records, individuals were identified as having been charged with drunken driving not less than 6 months or more than 12 months from the starting date of the study. Two random samples from this group were studied. In the first sample of 30 individuals, the respondents were asked in a face-to-face interview if they had been charged with drunken driving in the last 12 months. Of these 30 people interviewed face to face, 16 answered the question accurately. The...
