To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84

Answer:
6
Step-by-step explanation:
1/2 cup = 1 loaf of bread
1 cup = 2 loaves of bread
2 cup = 4 loaves of bread
3 cups = 6 loaves of bread
sorry i didn't know how to explain it in words
That would be 12<x
Its not 12 > x because that means that 12 is greater than x which is the same thing as x < 12.
Hope it helps
