Answer:
UCL (x bar) = 424
LCL (x bar) = 376
Step-by-step explanation:
Given:
Average calories contained, μ = 400
Standard deviation, σ = 30 calories
Sample size, n = 25
a) UCL (x bar) =
On substituting the respective values, we get
UCL (x bar) =
or
UCL (x bar) = 424
Similarly,
LCL (x bar) =
On substituting the respective values, we get
LCL (x bar) =
or
LCL (x bar) = 376
in log minus means divide
log 6 - log 3 = log (6÷3)
log 6 - log 3 = log 2
What does part a mean i dont understand
55 g x 25 days = 1375 grams
