Answer:
Tstatistic = - 3.068
Step-by-step explanation:
Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%
Mean titanium > 9.5%
Test statistic :
(m - μ) / (s/√n)
From the data: obtain the sample mean and standard deviation
From the data given ;
Calculate the same mean and standard deviation :
Using calculator :
Sample mean (m) = ΣX / n
Sample size (n) = 6
m = 47.1 / 6 = 7.85
Standard deviation (s) :
Using calculator = 1.317
Hence,
(m - μ) / (s/√n)
Tstatistic = (7.85 - 9.5) / (1.317/√6)
Tstatistic = - 1.65 / 0.5376629
Tstatistic = - 3.068
