You run a regression analysis on a bivariate set of data (n=19n=19). You obtain the regression equationy=1.761x+1.382y=1.761x+1.382with a correlation coefficient of r=0.876r=0.876 (which is significant at α=0.01α=0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 160 on the response variable.What is the predicted explanatory value?x = (Report answer accurate to one decimal place.)
(b) For a given set of trivariate data, the following results were obtained: X = 53, Y = 28, 6 (Y on X) =- 1.5, d (X on Y)=- 0.2. Find : (i) The two regression equations. (ii) the coefficient of correlation. (iii) The most probable value of Y when X=60.
The expected value of the sum or difference of two or more functions of a random variable X is the sum or difference of the expected values of the functions. That is, E[g(X)±h(X)] = E[g(X)] ± E[h(X)].
You test some components with a Weibull distribution at temperatures of 100 Celcius and 60 Celcius. At those temperatures you estimate a characteristic life of 15000 hours and 25000 hours respectively. hint: Boltzmann's constant is k = 8.617 x 10-5. Temperature in Celcius + 273.15 = temperature in Kelvin. If n is an integer, T(n) = (n – 1) a) Using linear regression, estimate the Arrhenius model parameters A and AH. b) Give the MTTF, median, and 90th percentile at T = 20 Celcius. Assume that the shape parameter is 0.5
(a) Let {B(t)} be the standard BM. Find E(B(t)) and Var(B(t)). (b) Let {X(t)} be a BM with a drift, with standard deviation parameter o and drift parameter u Find E(X(t)) and Var(X(t)). (c) Let {X(t)} be a geometric BM with standard deviation parameter o and drift parameter u. Find E(X(t)).
A medical researcher says that less than 85% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 300 adults in that country, 83% think that healthy children should be required to be vaccinated. At α=0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below. (a) Identify the claim and state H0 and Ha. Identify the claim in this scenario.

Consider the function f(x) = 2/T + 6 on the interval [4, 9]. Find the average or mean slope of the function on this interval. 0.4 By the Mean Value Theorem, we know there exists a c in the open interval (4, 9) such that f'(c) is equal to this mean slope. For this problem, there is only one c that works. Find it.
