Tongas Company applies revaluation accounting to plant assets with a carrying value of $1,600,000, a useful life of 4 years, and no salvage value. Depreciation is calculated on the straight-line basis. At the end of year 1, independent appraisers determine that the asset has a fair value of $1,500,000. The journal entry to record depreciation for year one will include a A debit to Accumulated Depreciation for $400,000. B debit to Depreciation Expense for $400,000. C debit to Depreciation Expense for $100,000. D credit to Accumulated Depreciation for $100,000.

a. At the 0.05 level of significance, is the mean life different from 7,516 hours? b. Compute the p-value and interpret its meaning. c. Construct a 95% confidence interval estimate of the population mean life of the light bulbs. d. Compare the results of (a) and (c). What conclusions can you reach? Hg = 7516 H 7516 What is the test statistic? ZSTAT = 1.5 (Round to two decimal places as needed.) What is/are the critical value(s)? 1.96, 1.96 (Round to two decimal places as needed. Use a comma to separate answers as needed.) What is the final conclusion? A. Reject Hg. There is not sufficient evidence to prove that the mean life is different from 7,516 hours. B. Reject Hg. There is sufficient evidence to prove that the mean life is different from 7,516 hours. C. Fail to reject Hg. There is sufficient evidence to prove that the mean life is different from 7,516 hours. D. Fail to reject Hg. There is not sufficient evidence to prove that the mean life is different from 7,516 hours. b. What is the p-value? 0.134 (Round to three decimal places as needed.) Interpret the meaning of the p-value. Choose the correct answer below: A. Reject Hg. There is sufficient evidence to prove that the mean life is different from 7,516 hours. B. Fail to reject Hg. There is sufficient evidence to prove that the mean life is different from 7,516 hours. C. Reject Hg. There is not sufficient evidence to prove that the mean life is different from 7,516 hours. D. Fail to reject Hg. There is not sufficient evidence to prove that the mean life is different from 7,516 hours. c. Construct a 95% confidence interval estimate of the population mean life of the light bulbs. (Round to one decimal place as needed.)

The linear circuit in Fig. 1 is a small-signal AC model of Fig. 2 CE amplifier. The bias of the current mirror and the base current to Q1 is adjusted so that Q1 & Q3 are: \begin{itemize} \item both in forward-active \item conduct $I_c$ of 100$\mu$A \end{itemize} Determine the values of the unknown resistances in Figure 1, if the Early voltages of the NPN and PNP devices are 75V and 50V, respectively. The current gain of the NPN is 100. Determine the open-circuit Voltage gain $A_{v(oc)}$ of this amplifier.
