A student in wildlife management studied trout habitats in the upper Shavers Fork watershed in West Virginia. The springtime water pH of 29 randomly selected tributary sample sites was found to have the following values: 6.2, 6.3, 5.0, 5.8, 4.6, 4.7, 4.7, 5.4, 6.2, 6.0, 5.4, 5.9, 6.2, 6.1, 6.0, 6.3, 6.2, 5.8, 6.2, 6.3, 6.3, 6.3, 6.4, 6.5, 6.6, 6.1, 6.3, 4.4, 6.7
Use a 90% confidence interval to estimate the mean springtime water pH of the tributary water basin around the Shavers Fork watershed.
Note: ¯x=5.89,s=0.64

to determine the unit cost your would divide the total cost by the number sold.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer is 33
