WebNov 4, 2024 · The area between scores z=1 and z=1.5 is 9.2. To find the z score that cuts of the highest 30%, add up from the right until you reach 30: 0.1+0.5+1.7+4.4+9.2+15 =30.9, therefore the z cutoff is 0.5. The middle 50% is not neatly enclosed by any set of z scores. The pair of -0.5 to +0.5 encloses 38.2% while the pair of -1 to +1 encloses 68.2%. WebSo instead of saying anything greater than or equal to 1.83 standard deviations above the mean, we could say anything less than or equal to 1.83 standard deviations below the means. So this is negative 1.83. And so we could look at that on this Z table right over here, negative 1.8, negative 1.83 is this right over here. So 0.0336. So there we ...

WebAug 29, 2024 · In step 2 we determine the level of significance equal to 5%, that is, if the p-value is less than 5%, the hypothesis is rejected, otherwise, if the p-value is greater than 5%, the hypothesis null remains. In this case, p = 31.7%, being greater than 5%, therefore the null hypothesis is maintained. References [1] Introduction to Hypothesis Testing WebThis problem has been solved!

WebMar 30, 2024 · Explanation: Given: P ( − 1.96 < z < 1.96), normal distribution z-tables have z-scores listed and their corresponding probabilities. The probability is the area under the curve from 0 to the probability value. The area under the full curve is From the z-tables: P (Z < 1.96) = .9750 P (Z < −1.96) = 0.0250 Webpenguinise • 1 min. ago. -CASDI is 592.06. Okay now that's just weird.
