**Z-Scores and Distribution Area****Question:**Find the z-scores for which 95% of the distribution's area lies between -z and z.**Answer Choices:**- ⭕ -0.96- ⭘ 0.95- ⭘ 0.475- ⭘ 1.96A check-box is ticked next to the option -0.96.**Explanation:**This question is about identifying the correct z-scores that encompass the central 95% of the standard normal distribution. In the context of the standard normal distribution, a z-score represents the number of standard deviations a data point is from the mean.In this case, we need to find the z-scores that mark the edges of the central 95% portion of the distribution. Statistically, for a standard normal distribution, the z-scores that cut off the lower and upper 2.5% (leaving 95% in the middle) are approximately -1.96 and 1.96.Thus, the correct answer should be `1.96` indicating that -1.96 and 1.96 are the z-scores between which 95% of the distribution's area lies.

The area between two boundaries is 95%. In, the remaining percentage 5% (=100%–95%) area, 2.5% area…

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
