11. Test the hypothesis that the population's mean is different from the sample's median value. Use a = 0.05. Null hypothesis (H,): Alternative hypothesis (H,): Type of Test: Critical value: or P-value: Test statistic: Conclusion: Do you reject the null hypothesis(yes or no)? (Show all work.)

A fitness club is going to conduct a questionnaire survey from a list of 120 members. Each member is assigned with a survey number and 6 members are selected randomly for an interview, (@) Identify the above sampling method. (b) How many digits of the survey number should be used?

The computer science department is making a new recruitment poster for computer science majors and would like to include information about the average salary of a software developer on the Treasure Coast estimate the average salary of a software developer, someone from the department collected a random sample of 10 software developersTheir salaries are listed belowAssume that the salaries of all software developers on the Treasure Coast are normally distributed 82,102 82,995 81,340 82,324 81,089 82,809 82,971 81,627 82,413 82,221 the point estimate, and the sample standard deviation, Round the solutions to four decimal places, if necessary a 95confidence level , determine the margin of error, and a confidence interval for the average salary of a software developer on the Treasure CoastReport the confidence interval using interval notationRound solutions to two decimal places, if necessary The margin of is given by E = confidence interval is given by

There are 38 activde telephone area codes in california. You want to choose an SRS of 10 of these area codes for a study of available telephone numbers. Label the codes 01 to 38 and use the simple random sample applet, table b or software to choose your sample.

A biologist argues that a certain species of fish found in Lake Tanzania in Africa should be classified in a different genus than the currently accepted genus for the species. A simple random sample of standard lengths of fully grown fish from the species in Lake Tanzania is given below: {116.2, 100.3, 118, 152.8, 141.3, 132.8, 95.6, 111.5, 95.2, 95.7} The population of alls such lengths is assumed to be close to normally distributed. Calculate the following interval estimates using this sample (note that the only one of the methods below can be used for a single sample in practice). Round answers to one decimal place accuracy. A 99% confidence interval for the mean of all fully grown fish of this type: type your answer... A 99% prediction interval for the length of one fully grown fish of this type is: type your answer... type your answer... type your answer...
