The following data represent the concentration of organic carbon (mg/L) collected from organic soil.

(Note:

x overbarxequals=17.93

mg/L and

sequals=7.63

mg/L)

(a) Determine a point estimate for the population mean.

(b) Construct a

99%

confidence interval for the mean concentration of dissolved organic carbon collected from organic soil.

a) the point estimate of population mean is equal to the sample mean

So point estimate for population mean is 17.63

b) xbar+/- t critical (s/n) is the confidence interval for mean

Since in the given data sample size is not mentioned

Substitute n we will get confidence interval for mean
