Question
The height of the basketball team is 1.7, 1.8, 1.9, 2.05, 2, 1.95, 2.1, 1.99, 2.02, 1.85. Is it okay to assume that these data come from a normal distribution with mean 1.9 and standard deviation 0.2?The height of the basketball team is 1.7, 1.8, 1.9, 2.05, 2, 1.95, 2.1, 1.99, 2.02, 1.85.

Explanation / Answer
here we can use SHAPIRO -WILK test to check normality of data by using R software.
x=c(1.7,1.8,1.9,2.05,2,1.95,2.1,1.99,2.02,1.85)
> shapiro.test(x)
Shapiro-Wilk normality test
data: x
W = 0.95651, p-value = 0.7455
> As we can see that P vale (.7455) is greater than level of significance (alpha=0.05 or 0.01)
Hence we accept null hypothesis and say that Data comes from normal population.
