According to a survey by the Better Sleep Council, 33% of people admit to dozing off at their workplace. Assume this proportion represents the true proportion all workers who doze off at their workplace. If a random sample of 100 workers is selected from this population, determine the standard error of the proportion.

Standard error of the proportion   = 0.04702

Step-by-step explanation:

Explanation:-

According to a survey by the Better Sleep Council, 33% of people admit to dozing off at their workplace

The sample proportion p = 33% = 0.33

q = 1-p = 1-0.33 = 0.67

Given a random sample of 100 workers is selected from this population

Given sample size 'n' = 100

The standard error of the Proportion  is determined by

Final answer:-

  Standard error of the proportion   = 0.04702

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

-2 is the right
