The table shows the solution to the equation |2x − 4| − 3 = 3:

step 1: |2x − 4| = −3 + 3
step 2: |2x − 4| = 0
step 3: 2x − 4 = 0
step 4: 2x = 4
step 5: x = 2

which is the first incorrect step?

a. step 1
b. step 2
c. step 3
d. solution is correct

Assume that the weight of cereal in a “12.6- ounce box” is n(μ, 0.22). the food and drug association (fda) allows only a small percentage of boxes to contain less than 12.6 ounces. we shall test the null hypothesis h0: μ = 13 against the alternative hypothesis h1: μ < 13. (a) use a random sample of n = 25 to define the test statistic and the critical region that has a significance level of α = 0.025.
