Consider the following hypothesis test. Ho: μ 1-u250 Hai μιιμ2>0 The following results are for two independent samples taken from the two populations. Sample 1 140 1 -25.4 2 22.3 Sample 2 n2 70 a. What is the value of the test statistic (round to 2 decimals)? b. What is the p-value (round to 4 decimals)? Use z-table. Use z-value rounded to 2 decimal places. c. with .05, what is your hypothesis testing conclusion? p-value is Select Ho
. (Ross 5.15) If X is a normal random variable with parameters μ-T0 and σ2-36, comput (a) P(X >5) (b) P(4 < X < 16) (c) P(X < 8) (d) P(X < 20) (e) P(X > 16)
2.11. Suppose that we are testing Ho: μ-μ0 versus H: >o with a sample size of n 15. Calculate bounds on the P-value for the following observed values of the test statistic: (a) to 2.35 (b)o 3.55 (c) 2.00 (d) to 1.55
9. IfX is a r.), distributed as N(μ, σ2), find the value of c (in terms of μ and σ) for which P(Xc 2-9P(X > c).
Please explain how to find the p-value In this exercise, test Ho : p = 0.5 vs Hq :p > 0.5, with p = 0.55 for different sample sizes. In parts (a)-(c), use Statkey or other technology to find the p-value. Click here to access Statkey. (a) P = b = 0.55 Round your answer to two decimal places. P-value= Are the results significant at the 5% level?
3.1 Find the p 50, x-: 9.5, s 7. In a test of Ho: μ vlaue. (ans. 0.1271) 10 vs. Ha: μ < 10, for a sample with n
Consider the following hypotheses: Ho: μ.. 27 Find the p-value for this test based on the following sample information. (You may find it useful to reference the appropriate table: table or ttable) 0.01 s p-value < 0.02 p-value 2 0.10 0.02 s p-value<0.05 O p-value < 0.01 0.05 s p-value < 0.10 b. x = 29, s= 6.6; n= 31 。p-value 0.10 0.05 s p-value<0.10 0 0.02 p-value < 0.05 0.01 s p-value <0.02 Op-value < 0.01 c, x =...
n = 36 Ho: u 220 x = 18 Ha: u < 20 S= 12 If the test is done at a .05 level of significance, the null hypothesis should not be rejected be rejected Not enough information is given to answer this question. None of the other answers are correct. OO
