You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 63%. with ha : p < 63% you obtain a test statistic of z = − 1.143 . find the p-value accurate to 4 decimal places.

p=0.1271

Step-by-step explanation:

Given :

            z = − 1.143

To Find :  Find the p-value accurate to 4 decimal places.

Solution:

We are given that You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 63%.

z = − 1.143

Refer the z table for p value

p=0.1271

Hence the p-value accurate to 4 decimal places is 0.1271

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
