Say you think that an output will be normally distributed with mean 1 and variance 1 You use the test statistic r- 1 a) At what values of x would you reject the null if your a value is set to 0.05. Hint: there are two values xŻ and xk such that if x x; or if x x, we would reject. b) Say that in actuality, z is drawn from an exponential distribution with mean 1. Thus the null...

1. Choose a data set of your own:?Response or dependent variable (Y)?At least 3 or more independent variables (X1, X2, X3, ... etc.) that you believe has an influence on Y.?At least 40 observations or data points?If there are categorical variables, model them appropriately2. Fit a multiple regression model. ?Interpret the model equation?Are all the chosen variables significant? Discuss.?Check for model assumptions and make appropriate comments.?How good is the model?

Option 1 or 2.
Option 1: Use the NOAA data set provided, to examine the variable DX32. DX32 represents the number of days in that month whose maximum temperature was less than 32 degrees F. The mean of DX32 during this time period was 3.6. Using Excel, StatCrunch, etc, draw a histogram for DX32. Does this variable have an approximately normal (i.e. bell-shaped) distribution? A normal distribution should have most of its values clustered close to its mean. What kind...

1. The FBI compiles data on robbery and property crimes and publishes the information. A ran- dom sample of pickpocket offenses yielded the losses, in dollars, described by the following summary statistics: * = 513.32, s = 262.23, and n = 20. We want to use this data to make inference on u, the mean loss in all pickpocket offenses in the U.S. Assume a = 0.05 and the data comes from a normal distribution with unknown variance, answer the...

Please do exercise 129:
Exercise 128: Define r:N + N by r(n) = next(next(n)). Let f:N → N be the unique function that satisfies f(0) = 2 and f(next(n)) =r(f(n)) for all n E N. 102 1. Prove that f(3) = 8. 2. Prove that 2 <f(n) for all n E N. Exercise 129: Define r and f as in Exercise 128. Assume that x + y. Define r' = {(x,y),(y,x)}. Let g:N + {x,y} be the unique function that...

OPTION A (Basic): Complex Numbers
A complex number, c,
is an ordered pair of real numbers
(doubles). For example, for any two real numbers,
s and t, we can form the complex number:
This is only part of what makes a complex number complex.
Another important aspect is the definition of special rules for
adding, multiplying, dividing, etc. these ordered pairs. Complex
numbers are more than simply x-y coordinates because of these
operations. Examples of complex numbers in this...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
