A sample of 81 account balances of a credit company showed an average balance of $1200 with a standard deviation of $126.
a.
Formulate the hypotheses that can be used to determine whether the mean of all account balances is significantly different from $1150.
b.
Compute the test statistic.
c.
Using the p-value approach, what is your conclusion? Let α = .05.

a.
H0: μ = $1150
Ha: μ ≠ $1150
b.
t = 3.571
c.
p-value (almost zero) <.005; therefore, reject H0 and conclude that the mean balance is significantly different from $1150.
