Find the area under the standard normal curve to the left of z = 1.88, P(z < 1.88). (Give your answer correct to four decimal places.)

Just find 1.88 in your chart or in your table, which you surely must have.

If not, here is an online standard normal curve ....

Why was the math book sad?

Because it had too many problems!

Speaking of problems, let's solve this one. To find the area under the standard normal curve to the left of z = 1.88, we can use a nifty little thing called a z-table.

So, let's consult our z-table for the area to the left of 1.88.

And the answer is... drumroll please... 0.9693!

That's right, the area under the standard normal curve to the left of z = 1.88 is approximately 0.9693.

Now, go forth and conquer those math problems, just don't let them make you sad like that math book.

To find the area under the standard normal curve to the left of z = 1.88, we need to use the standard normal distribution table or a statistical calculator.

Step 1: Look up the z-score 1.88 in the standard normal distribution table.

By looking up the value 1.88 in the standard normal distribution table, we find that the area to the left of z = 1.88 is 0.9693.

Step 2: Round the result to four decimal places.

Rounding 0.9693 to four decimal places, we get 0.9693.

Therefore, the area under the standard normal curve to the left of z = 1.88 or P(z < 1.88) is approximately 0.9693.

To find the area under the standard normal curve to the left of z = 1.88, we can use a standard normal distribution table or a statistical calculator.

Using a standard normal distribution table:
1. Look for the z-score closest to 1.88 in the left column of the table. The closest value is 1.8.
2. Look for the column with the heading 0.08 in the top row of the table. The value in this intersection is 0.9641.
3. This value represents the area to the left of z = 1.8, which is slightly less than 1.88. To get the area to the left of z = 1.88, we need to add the remaining area (0.08) to 0.9641.
4. So, the area under the standard normal curve to the left of z = 1.88 is approximately 0.9641 + 0.08 = 1.0441.

Using a statistical calculator:
1. Type in the z-score 1.88 into the calculator.
2. Use the cumulative distribution function (CDF) to find the area to the left of z = 1.88.
3. The result will be given as a decimal value, which represents the area under the standard normal curve to the left of z = 1.88.

The answer, correct to four decimal places, is approximately 1.0441.
