(o) Formulate the hypotheses (in dollars) that can be used to determine whether the mean of all account balances is significantly different from $1,140. (Enter i= for + as needed. (b) Compute the test statistic. (Round your answer to three decimal places.) x (c) Uxing the p-value approach, what is your conciusion? Let a =0.05. Find the p-value. (hound your answer to four decimal places) p.value = State vour condusion. Do not reject H0. There is sueficient evidence that the mean balance is significantiy different fram $1,140 Reject H8. There is insumcient evidence that the mean bolance is significantly different from 11,140 . Reject H0. There is wifficent evidence that the mean balance is sprifcantiv different from $1,140. Do not repect H0. There is imulficient evidence that the mean balance is significantly different foom
