Test H0: π = 0.25 versus HA: π ¹ 0.25 with p = 0.33 and n = 100 at alpha = 0.05 and 0.10.
Y~Bin(n,p). 15 of 100 samples are successes. Test the null hypothesis H0 : p = 0.10 against the alternative Ha : p > 0.10 at level alpha = 0.1 Find the p value.
We wish to test H0: = 0 versus Ha: > 0. If we calculate a test statistic of = 0.6, then my p-value will be closest to 0.003 0.300 0.600 0.950 When estimating , the proportion of voting age citizens who will vote for Candidate A, political researchers calculate the 90% confidence interval (0.67, 0.73). If we were to also test the hypotheses H0: = 0.666 versus Ha: 0.666 using a significance level of = 0.10, we would decide to accept H0. reject H0. not reject...
In a test of the hypothesis H0: μ=48 versus Ha: μ>48, a sample of n =100observations possessed mean X̄ =47.4 and standard deviation s=4.6. The p-value for this test is .902 Interpret the result. Select the correct choice below and fill in the answer box to complete your choice.(Round to three decimal places as needed.) A) The probability (assuming that Ha is true) of observing a value of the test statistic that is at most as contradictory to the null...
A hypothesis test is used to test the hypotheses H0: μ = 10.5 versus HA: μ > 10.5 where μ = the mean weight of a one-year old tabby cat. Based on a random sample of 21 cats, a p-value of 0.0234 is found. a) Using α = 0.05, what is the conclusion for this test, reject or fail to reject the null hypothesis? b) Based on your answer to part b, what type of error did you possibly make,...
For a test of H0: μ = 15 versus Ha: μ ̸= 15, the value of the test statistic is t = 3.472 based on a sample of 9 observations. Based on Table D, how would you express the P-value?
In testing H0: µ = 100 versus Ha: µ ╪ 100 versus using a sample size of 325, the value of the test statistic was found to be 2.16. The p-value (observed level of significance) is best approximated by 0.0154 0.9692 0.4846 0.0308 0.007
Calculate the test statistic and p-value for each sample.(Round your test statistics to 2 decimal places and p-values to 4 decimal places.) Note: xnumber of successes Test Statistic p-value (a) H0: p=0.60 versus Ha: p > 0.80, α=.05, x=56, n = 80 (c) Ho, p-0.10 versus HA: p 0.10, a-.01, x-3. n-100
Consider the following hypotheses: H0: μ ≤ 420 HA: μ > 420 Find the p-value for this test based on the following sample information.
