Fill in the blank: 50% of the area under the standard normal curve is between -0.5 and _____________.
Is -0.5 a Z score, T-score or raw score?
I am guessing -.5 is a z-score right?
Dude, stop violating the honor code.
Try to watch the videos and figure out how to do the homework yourself.
To fill in the blank, we need to find the z-score corresponding to the given percentage.
The standard normal curve is a bell-shaped curve with a mean of 0 and a standard deviation of 1. The area under the curve represents the probabilities.
To find the z-score corresponding to 50% of the area, we first need to understand that the standard normal distribution is symmetric. This means that 50% of the area falls to the left of the mean, and the remaining 50% falls to the right of the mean.
Since the question states that 50% of the area is between -0.5 and some value, we can conclude that the value we need to find is positive since it falls to the right of the mean.
To find the z-score corresponding to a given percentage, we can use a Z-score table or calculator. The z-score represents how many standard deviations away from the mean a particular value is.
In this case, because we are dealing with a standard normal distribution, the z-score we are looking for is the value that corresponds to the area of 0.5.
Using a z-score table or calculator, we can find that the z-score corresponding to an area of 0.5 is 0.
Therefore, the answer to the blank is 0.
