First change the percent to a decimal 10% = 0.1 8.5% = 0.085
then subtract 20 - 0.1 = 19.9
then add 19.9 + 0.085 = 19.985
hope it help ☺
172 ÷ 4 = 43 miles per hour
43 ÷ 5 = 10.75 miles per 12 minutes
Answer:
Step-by-step explanation:
a) The null hypothesis states that
The production line operation fills cartons with laundry detergent to a mean weight of 32 ounces.
H0 : µ = 32
The alternative hypothesis states that
The production line operation overfills or under fills cartons with the laundry detergent to a mean weight of above or below 32 ounces.
Ha : µ ≠ 32
b) when the calculations are done and the p value is determined, then it would be compared with the level of significance
When the significance level is lesser than the p value, we do not reject H0 because there is no sufficient evidence to conclude that the production line operation overfills or under fills cartons.
c) When the significance level is greater than the p value, we would reject H0 because there is sufficient evidence to conclude that the production line operation overfills or under fills cartons.
