### Conceptual Overview: Compute and visualize probabilities for the standard normal distribution using numerical inputs for z and p.This graph provides the lower tail probabilities for the standard normal distribution.Change the value of z or p in the boxes below to update the graph. When you change one value, the other value will update automatically. Observe how the shaded area in the lower tail changes with different values of z or p.#### Input Fields:- **z:** -1.645- **p:** 0.05#### Graph Explanation:The graph is a standard normal distribution curve (bell curve) centered at 0. The x-axis ranges from approximately -3 to 3. The shaded area on the left side of the curve represents the lower tail probability which corresponds to p = 0.05. The z-score at the edge of the shaded region is marked as -1.645.#### Questions:1. **What is the z-score for an upper-tail probability of .10?** - a. 1.645 - b. 1.96 - c. 1.282 - d. 2.33 - **Selected Answer:** d2. **What is the probability for the region -1.75 ≤ z ≤ 1.5?** - a. .973 - b. .613 - c. .586 - d. .893 - **Selected Answer:** d#### Authors and Credits:- **Created by:** Gary H.

K A commuter tallied the time to work for 200 days and found that it resembled a normal curve. The mean time was 50 minutes, and the standard deviation was 2 minutes. For the 200-work-day experiment, find the percent of time commuting to work less than 44 minutes. 44 Minutes to Commute to Office 1 46 48 68%- 95% 99/7% 50
Calculate the z-score representing the bottom 10% of an approximately normal distribution. (Use a table or technology. Round your answer to two decimal places.)
Select all true statements below (Multiple or none can be true). With a large, representative sample, the histogram of the sample data will follow the normal curve closely. If two lists of numbers have exactly the same average of 50 and SD of 10, then the percentage of entries between 40 and 60 must be exactly the same for both lists. Half of a list of numbers is always below its average. The median and average of a list of numbers are not necessarily close together.

Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score. 0.05 Click to view page 1 of the table.
