A z-darkened score’s area to the **left** (z is greater than the mean). **Step** 1: After the tenth decimal point, divide the provided decimal into two halves. If you’re given 0.46, for example, divide it into 0.4 + 0.06. **Step** 2: In the z-table, look up your decimals from **Step** 1. **Step** 3: Take the z-value you determined in **step** 2 and multiply it by 0.500.

Similarly, How do you find the area to the left and right of Z?

We can easily look up the **number** -1.07 in the **z-table to identify** the **region** to the right of the **z-score**: What exactly is this? The **region** to the left of z = -1.07 is represented by this. As a result, the right-hand area is computed as 1 – 0.1423 = 0.8577.

Also, it is asked, How do you find the area to the left of Z in Excel?

“**Find the region** to the **left** of the **normal curve**.” The **region** to the **left** of a z-score is given by =NORMSDIST(z-score). “**Find the region** to the right of the **normal curve**.” Subtract 1 from the area to the **left** of a given z-score to obtain the area to the RIGHT of that z-score.

Secondly, What is the area in the left hand tail of the standard normal curve below Z?

We scan through the body of a **regular normal table** “**backwards**” to **identify a region** that is closest to 0.025. A z-score of 1.96 corresponds to a left-tail area of 0.025.

Also, Why the proportion of the area to the left of z =- 2.58 is 49?

**Z-tables enable** for readings up to the **hundredth place** of a score, allowing for four or five **significant numbers** in regions. This is done by reading through the relevant row from the tenth **place** on the left axis to the **hundredth place**. This explains why the region to the left of z = -2.58 has a percentage of.

People also ask, How do you find the z-score without a table?

(x – ) z = (x – ) z = (x – ) z = (x – ) z The **exam** has a 150-point mean () and a 25-point **standard deviation** (). z = (x – ) / z = (x – ) / z = (x – ) / z = (x – ) / z = (x – ) / z = (x – )
