An important source of income for a large international banking company is home loans. The loan manager at a branch keeps track of the number of loan applicants who visit the branch's loan department per week. Over the last year, the loan manager accumulated the data shown in the table below. From previous years, the manager believes that the distribution of the number of customers has a Poisson distribution loan officer's belief is correct using a significance level of 0.05. an average of 3.6 loan applicants per week. Determine if the Number of Customers 0 1 2 3 4 5 26 Frequencies 1 7 10 4 10 11 13 State the appropriate null and alternative hypotheses. Choose the correct answer below. O A. Ho: The population mean is equal to 3.6. HA: The population mean is not equal to 3.6. B. Ho: The population is Poisson distributed with mean equal to 3.6. HA: The population is not Poisson distributed with mean equal to 3.6. O C. Ho: The population is not Poisson distributed with mean equal to 3.6. HA: The population is Poisson distributed with mean equal to 3.6. O D. Ho: The population mean is not equal to 3.6. HA: The population mean is equal to 3.6. The test statistic is y? =D.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
