Thus, p–value = P(Z > 2.074) = .0192 and so the company can reject the null hypothesis at the .05 significance level conclude the Vitamin C reduces the mean recovery times. Let p = proportion who renew. Then, the hypotheses are H0: p = .60, Ha: p ≠ .60. The sample proportion is = 108/200 = .54, and so the computed test statistic is z = –1.732. The p–value is given by = …

Clearly the statistical power of this analysis was limited compared to the much larger main analysis. The only detectable effects on hand preference in this multivariable model were sex (OR=0.78, p=0.003), and a weak effect of being born outside the UK (OR=1.6, p=0.038). The p-value for the likelihood ratio of the model was p=0.014.

The z-value of an organism is the temperature, in degrees Fahrenheit, that is required for the thermal destruction curve to move one log cycle. While the D-value gives us the time needed at a certain temperature to kill an organism, the z-value relates the resistance of an organism to differing temperatures. So, the z-value allows us to calculate a thermal process of equivalency, …

Relationship between ( and p-value Decision p-value < ( Reject H0 p-value > ( Do Not Reject H0 In the z-table, 1.75 standard deviations corresponds to a probability of 0.4599, so our one-tailed p-value is approximately 0.5 – 0.4599 = 0.0401. Since this value is smaller than 0.05, we reject the null hypothesis, and conclude that the true population mean is less than 2.8 feet. Note that …

From the z table, we find the value of z to be 1.960. So the CI is z*SE=.05(1.960)(.0077)= (.035, .065) G.

2009-08-25 · Z = 1.00 – 0.524 = 0.476 = 0.48. Looking up that z value in the table for area under the normal curve, look for z = 0.4, move to the right to the column marked “8”, which gives: P = .3156 or 31.56% of the total Shaver Mfg. employees. Since the question was posed as a fraction, the answer is “nearly one-third”.
