Concept explainers

Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

Expert Solution

Step 1 Introduction:

Confidence Interval: In statistics, we can say a range of values of the population parameter will lies within it with some confidence is known as Confidence Interval.

Confidence Level: Confidence level is nothing but (1 - alpha)% which explains how much you are confident that the result will fall within the certain range.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
The owner of a fish market has an assistant who has determined that the weights of catfish are normally distributed, with a mean of 3.2 pounds and a standard deviation of 0.8 pound. If a sample of 25 fish yields a mean of 3.1 pounds, what is the Z-score for this observation? Question 3 options: 1) 2.500 2) 0.625 3) -0.625 4) 1.250
Question 1 The mayor is interested in finding a 98% confidence interval for the mean number of pounds of trash per person per week that is generated in the city. The study included 220 residents whose mean number of pounds of trash generated per person per week was 36.6 pounds and the standard deviation was 7.7 pounds. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ? v distribution. b. With 98% confidence the population mean number of pounds per person per week is between and pounds. c. If many groups of 220 randomly selected members are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person per week and about percent will not contain the true population mean number of pounds of trash generated per person per week.
