4. The effective annual return can be calculated in one of two ways: (1 + Monthly return)12 – 1: This is the compounded annual return, which is preferable, because it makes allowances for the reinvestment of each month’s earnings. 12*Monthly return: This method is often used by banks. Create a spreadsheet that graphs the difference between these two versions of the effective annual return as the monthly return ranges between 1% and 10% (large rates differential). Repeat the exercise for...

To decide whether two different types of steel have the same true average fracture toughness values, n specimens of each type are tested, yielding the following results. Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n 100. (Round your answer to four decimal places.) Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n- 400. (Round your answer to four decimal places.) Is the small...

Solve two different ways, DO NOT USE NORMAL TABLE
4) The lifetime in hours) of a certain type of light bulb is approximately normal with a mean of 1,000 hours and a standard deviation of 70 hours. What is the probability that the bulb will last between 1050 and 1150 hours? Assume normal distribution. Solve the problem in two (2) completely different ways * 1 way using normal table and 1 way NOT using normal table. (9 marks)

For the hydrogen atom: a) How many different 3d states are there? b) What physical property of properties (as opposed to quantum numbers) distinguishes them, and what different values may this property or these properties assume? c) Identify all the different total angular momentum states (sets of {j, mj}) that a 3d electron can occupy. d) An external magnetic field much stronger than the atom's internal, self-generated magnetic fields is applied to the atom. Into how many distinct energy levels...
