406.0 gram setting.
N= 40 bag sample had a
mean of 405.0 grams.
A level of significance of 0.02
the standard deviation is known to be 26.0
mean = Np = 40 * 0.02 =
Z = (variate - mean)/standard deviation
Z = 406 - 405)/26 = 0.038

The ribbon cost per foot $0.6 per foot
Step-by-step explanation:
Total number of ribbon used = (5.75 + 11.75) = 17.50 feet
17.50 feet of ribbon cost = $10.50
1 foot of ribbon cost = x
Cross Multiply
17.50 × x = 1 foot × $10.50
x = 1 foot × 10.50/17.50
x = $0.6
The ribbon cost per foot $0.6 per foot
