Let X = b(10000, p), x = 5220, H0 is that p = 0.5, H1 is that p does not equal 0.5. Should we accept or reject H1 at 95% confidence level?
Suppose a researcher is testing the hypothesis Ho: p = 0.6 versus H1:p*0.6 and she finds the P-value to be 0.29. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. O A. If the P-value for a particular test statistic is 0.29, she expects results no more extreme than the test statistic in about 29 of 100 samples if the null hypothesis is true. OB. If the P-value for a particular test statistic...
Consider testing H0: p=0.1 versus H1: p<0.1. If the standardized critical value is -1.00 (i.e. the standardized rejection region is from negative infinity to -1.00) then what was the selected significance level (alpha)? (Answer as a probability, not a percent. Record your answer accurate to at least the nearest THIRD decimal place with standard rounding.)
To test H0: σ = 40 versus H1: σ < 40, a random sample of size n=27 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 28.8, compute the test statistic (b) if the researcher decides to test this hypothesis at the a=0.05 level of significance, use technology to determine the P-value.(c) Will the researcher reject the null hypothesis?
#1 part A.) To test H0: μ=100 versus H1: μ≠100, a random sample of size n=20 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below. (aa.) If x̅=104.4 and s=9.4, compute the test statistic. t0 = __________ (bb.) If the researcher decides to test this hypothesis at the α=0.01 level of significance, determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in...
3. X = b(200, p), p0 = 0.6, x = 155, the significance level is α = 0.01. The null hypothesis is p = p0, the alternative hypothesis is p > p0. Should we accepts or reject the alternative hypothesis look below: I know the answers to this problem. I just need help on finding the critical value z. PLEASE EXPLAIN
In order to test Ho: Mo = 40 versus H1:# 40, a random sample of size n = 25 is obtained from a normal population with a known o = 6. My x-BAR mean is 42.3 from my sample. Using a TI 83/84 calculator, calculate my P-value with the appropriate Hypothesis Test. Use a critical level a = 0.01 and decide to Accept or Reject Ho with the valid reason for the decision. My P-value greater than a Alpha, so...
In order to test HO: µ0 = 40 versus H1: µ ≠ 40, a random sample of size n = 25 is obtained from a normal population with a known σ = 6. My x-BAR mean is 42.3 from my sample. Using a TI 83/84 calculator, calculate my P-value with the appropriate Hypothesis Test. Use a critical level α = 0.01 and decide to Accept or Reject HO with the valid reason for the decision. A. My P-value greater than...
Consider the hypotheses below. H0: μ=50 H1: μ≠50 Given that x overbar equals x=51,s=10,n=25,and alpha equals=0.05, answer the questions below. a. What conclusion should be drawn? b. Use technology to determine the p-value for this test. a. Determine the critical value(s). The critical value(s) is(are) nothing. (Round to three decimal places as needed. Use a comma to separate answers as needed.) Determine the test statistic, (Round to two decimal places as needed.) What conclusion should be drawn? Choose the correct...
33.6 34.8 30.5 36 35.8 Test the hypotheses H0: μ = 35 versus H1: μ < 35, using α= 0.05. What is the P-value Should the null be rejected or fail to reject
