step4 Step 4Now that we have found x² = 48.341 with df = 2, we can determine our P-value.Recallthat the P-value for a chi-square test of homogeneity is the area under the appropriate chi-square curve and to the right of the calculated value of the test statistic. Use technology to determine the P-value and round the result to three decimal places.P-value=Submit Skip (you cannot come back)

The scores of adults on an IQ test are approximately normal with mean 100 and standard deviation 15. Brad Pitt scores 118 on such a test. He scores higher than what percent of all adults? What if his score were 95? Find the value for Z and show the area under the standard normal curve.
I do not entirely understand what it means to find the s-score for an area of 0.1 (for the 10th percentile). I know I need to look at the z-score table but I always seem to get the answer wrong- please help. Thank you
What is the cumulative area from the left under the curve for a z-score of -0.55? What is the area on the right of that z-score? Hint: You will have two answers I need this by excel only otherwise I'll dislike so i suggest u to skip if u can't solve by excel
Can you please help me understand how the answer arrived at .975 for the area under the curve in reference to the follwing question? The solution in Bartleby mentions that the cummulative area is .975 to the left and I don't understand where that value come from.

Suppose the lengths of human pregnancies are normally distributed with μ=266 days and σ=16 days. Complete parts (a) and (b) below. A) The figure to the right represents the normal curve with μ=266 days and σ=16 days. The area to the left of X=250is 0.1587. Provide two interpretations of this area. Provide one interpretation of the area using the given values Provide a second interpretation of the area using the given value b) The figure to the right represents the normal curve with μ=266 days and σ=16 days. The area between x=230 and x=280 is 0.7970. Provide two interpretations of this area. Provide one interpretation of the area using the given values. Provide a second interpretation of the area using the given values (Type integers or decimals. Use ascending order.)
continuing off of that question: 4. In the next two parts of the question, you will calculate the approximate area under the curve using the right end-points of the sub-intervals. Complete the following table (for the second column, you should only have to do one calculation from scratch, since you have already calculated three of the numbers earlier in the question). x1 : f (x1) : x2 : f (x2) : x3 : f (x3) : x4 : f (x4) : 5. Now calculate the approximate area under the curve using the formula Approximate area under curve : 6.In the next two parts of the question, you will calculate the approximate area under the curve using the mid-points of the sub-intervals. Complete the following table x1 : f (x1) : x2 : f (x2) : x3 : f (x3) : x4 : f (x4) : 7.Now calculate the approximate area under the curve using the formula Approximate area under curve :
