PLEASE PUT CLEAR AND EASY TO READ RESPONSES! THANK YOU! 1. Below are the graphs of a standard Normal distribution and a t-distribution with 3 degrees of freedom. (a) Indicated which graph is which and explain how you know. Dotted graph Solid graph- 3-2 1 (b) On the same figure sketch a graph of a t-distribution with 1 degree of freedom. 2. Find the critical value for each of the following confidence intervals: (a) 95% confidence interval with 8 degrees...
Plot the data for the measurements given below. Being able to create graphs and interpret graphs is an integral part of any science course. You can use the graph paper included in this document, an Excel spreadsheet or your own graph paper. The time measurements are the x-axis coordinates. The temperature measurements are the y-axis coordinates. Space your axes in consecutive intervals such as units of 1,5 or 10. Make sure to label your axes with the appropriate information, including...
Different types of bees are very similar in appearance. Statistical analysis of certain measurements, like wing width, can be used to distinguish one kind of bee from another, Using a random sample of 10 bees, 95% confidence interval for the wing width (in millimeters) of an unknown species of bees from a certain hive is taken and found to be (2.8236, 2.8904). Which of the following conclusions can be made? A) We are 95% confident that the mean wing width...

Gasoline mileage (mpg) was measured on several cars of each of four different makes (coded 1, 2, 3 and 4). The make of each car is stored in the first column, and the mileage for each car is stored in the second column, of Table A. You need to conduct an analysis of variance to see if there are differences among the four makes in gasoline mileage. You should also estimate the mileage of each of the four makes of...
(36) Estimators are used in two different ways: point estimation and confidence estimation. (1) True. (2) False. (37) Which of the statements about large-sample estimation is correct? (1) An estimator should be unbiased and the spread (as measured by the mean) should be as small as possible. (2) The distance between an estimate and the true value of the statistic is called the error of estimation. (3) The 95% Margin of error is: 1.96 x Standard error of the estimator. (4) A good confidence interval is as...
21. The following graphs show the scatterplot relationships for two different sets of data. Describe each graph as Linear or Non-Linear by circling the correct choice. For each graph also choose which regression equation would be the best choice to use for developing a mathematical model to describe the data, i.e. y=mx+b, y= ar? +bx+c y=ca'. [4 Points). Linear or Non-Linear Linear or Non-Linear Regression Equation: Regression Equation: 22. Write the equation of a quadratic that has a vertex at...
1. A random sample of n measurements was selected from a population with standard deviation σ=13.6 and unknown mean μ. Calculate a 90 % confidence interval for μ for each of the following situations: (a) n=45, x¯¯¯=89.8 ≤μ≤ (b) n=70, x¯¯¯=89.8 ≤μ≤ (c) n=100, x¯¯¯=89.8 ≤μ≤ (d) In general, we can say that for the same confidence level, increasing the sample size the margin of error (width) of the confidence interval. (Enter: ''DECREASES'', ''DOES NOT CHANGE'' or ''INCREASES'', without the...
do the following problem from the text book. please use R software and oost the code along woth answes and any graphs that you are required to make, olease read both pictures 13-10. An article in Environment International [1992, Vol. 18(4)] described an experiment in which the amount of radon released in showers was investigated. Radon-enriched water was used in the experiment, and six different orifice diameters were tested in shower heads. The data from the experiment are shown in...
A major television network is considering three potential comedies: Bobby's Bunch, Her Four Husbands, and I like Larry. A pilot ("first") episode for each has been videotaped. The network is trying to determine whether some of these shows are better liked than others and whether younger viewers (under age forty) tend to have different opinions than older viewers (age forty and above). The network randomly selected an equal number of people under age forty and age forty and above. It...
