Part D only please and solve without using excel only the Normal Curve table The image depicts a standard normal distribution table, often used in statistics to determine the probability of a value occurring within a normal distribution. Each entry in the table corresponds to the cumulative probability of a standard normal variable z.### Explanation of the Table:#### Structure:- The table is organized with z-scores displayed in the first column and the top row. - The first column contains the integer and first decimal place of the z-score, ranging from 0.0 to at least 3.6.- The top row includes the second decimal place of the z-score, ranging from .00 to .09.#### Content:- The cell at the intersection of a row and a column gives the cumulative probability for the corresponding z-score.- For example, the intersection at z = 0.0 and .01 (0.01) gives a probability of 0.0038, indicating that 0.38% of the data lies below this z-score.- The values increase as you move rightward across a row or downward down a column, representing higher cumulative probabilities.#### Usage:- This table is vital for determining z-scores in various statistical analyses, allowing one to ascertain probabilities related to specific data points within a standard normal distribution.- It is particularly useful in hypothesis testing and confidence interval estimation.### No Graphs or Diagrams:- The table includes no graphs or additional diagrams. It purely lists numerical values related to the standard normal distribution. **4.99 DELIVERY TIMES FOR ONLINE ORDERS**Refer to the *Journal of Marketing Research* (October 2019) study of delivery times for online orders, Exercise 2.88 (p. 88). Recall that a major apparel retailer has two distribution centers (DCs) to fulfill all its online orders—one located in the eastern United States and one in the western United States. Based on the study, we can assume that the delivery time $x$ (in business days) for online orders fulfilled by the eastern DC is normally distributed with mean $\mu = 5.22$ and standard deviation $\sigma = 0.77$. Similarly, assume that the delivery time $x$ for online orders fulfilled by the western DC is normally distributed with mean $\mu = 6.95$ and standard deviation $\sigma = 0.55$.- **a.** For online orders filled by the eastern DC, find $P(x \leq 5)$.- **b.** For online orders filled by the eastern DC, find $P(4 \leq x \leq 7)$.- **c.** For online orders filled by the eastern DC, find the value $a$, so that $P(x > a) = 0.30$.- **d.** Repeat parts a-c for online orders filled by the western DC.

Given that: For eastern DC, the mean and standard deviation are: μ=5.22σ=0.77 For western DC, the…

A least squares regression model performed to predict the selling price of houses found the following equation: Pricê = 169.328+35.3Area + 0.718Lotsize - 6543Age where Price is in dollars, Area is in square feet, Lotsize is in square feet, and Age is in years. The R2 is 0.92. One of the following interpretations is correct. Which is it? Explain why. a.) Each year a house Ages, it is worth $6543 less. b.) Every extra square foot of Area is associated with an additional $35.30 in average price, for houses with a given Lotsize and Age. c.) Every dollar in price means Lotsize increases 0.718 square feet. d.) This model fits 92% of the data points exactly.

Recap When Not In Use Use In Ventilated Area • Conforms To ASTM D-4236 MARKER Chisel Point 20. An example of the vertical-horizontal illusion is shown in the figure. Although the two lines are exactly the same length, the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line.
