4 of 4G3 10.2.21 Given the null and deviatons shown tothe right, conduct a hypothesis Him-m<0 sample Ho: μ,-μ2 20x1-128x2-145 σ2 .18 standard σΊ9 test using an alpha level equal to 0.05. Calculate the value of the test statistic. (Round to two decimal places as needed.) in the AI part 1 F
9 Test the null hypothesis Ho : u = 3.0against the alternative hypothesis HA: U < 3.0 , based on a random sample of 25 observations drawn from a normally distributed population with ū = 2.8 and o = 0.70. a) What is the value of the test statistic? Round your response to at least 3 decimal places. Number b) What is the appropriate p-value? Round your response to at least 3 decimal places. Number c) Is the null hypothesis...
QUESTION 17 Which of the following leads to rejecting the null: O Tobt| < alpha o Terit > Tobt| O Tcrit) < Tobt| Sig. > alpha
When performing an F-test, if the null hypothesis is H. : B1 = B2 = 0 what is the alternative hypothesis? (B1 < 0 and B2 > 0) or (B1 > 0 and B2 < 0) B1 + 0 and/or B2 + 0 O B1 + 0 and B2 + 0 O (B1 + 0 and B2 = 0) or (B1 = 0 and B2 + 0)
A statistician was testing the following hypothesis: Ho: u < 501.3 The p-value approach was to be used with a sigma of 32.2. A sample of size of 51 gave a sample mean of 505.2. Find the p-value to 4 decimal places.
Suppose that NoP(X5)6 and P(X 2):2 find P( 3< X < 4).
Assume the null hypothesis was rejected with alpha being 0.05. What happens to the null if alpha gets changed to 0.10? a) we do not know for sure b) the null gets rejected for sure c) the null doesn't get rejected for sure d) and e) were saying something about a 1% probability that the null gets rejected or doesnt get rejected ( im pretty sure the answer is between a, b or c)
Problem 8. Suppose that XGeom(p) and Y ~ Geom(r) are independent. Find the probability P(X <Y).
