Question

in a newspapers survey of 491 people, 53.2% said that we should replace passwords with biometric security, such as fingerprints. the accompanying statdisk display results from a test of the claim that half of us say that we should replace passwords with biometric security. use the normal distribution as an approximation to the binomial distribution. use the display and a 0.10 significance level to complete parts (a) through (e).
sample proportion: 0.5315582
test statistic, z: 1.3990
critical z: ±1.6449
p - value: 0.1618
b. what is the test statistic?
z = 1.40
(round to two decimal places as needed.)
c. what is the p - value?
p - value =
(round to three decimal places as needed.)

Explanation:

Step1: Identify the P - value from the given display

The P - value is directly provided in the Statdisk display.

Answer:

\(0.162\) (rounded to three decimal places as \(0.1618\approx0.162\))
