Assume normal distribution. 225, 240, 215, 206, 211, 210, 193, 250, 225, 202. Please round to the nearest tenth and write your answer in the form ( , ); for example (31,34) or (25,46). Do not type in any extra spaces.9. Assume that we want to construct a confidence interval. Determine whether you should use the t-distribution or the normal distribution to find it, based off of the following information. In this problem, let n be the sample size. n = 23, the standard deviation is unknown, the population appears to be normally distributedo T-Distributiono Normal Distributiono neither of the methods studied by us can be used10.

A university of dean of students wishes to estimate the average number of hours students spend doing homework per week. The standard deviation from a previous study is 6.2 hours. How large a sample must be selected if he wants to be 99% confident of finding whether the true mean differs from the sample mean by 1.5 hours?14. If the variance of a national accounting examination is 900, how large a sample is needed to estimate the true mean score within 5 points with 99% confidence?

In this part of the project, you will be modelling the behavior of a resistor-capacitor (RC) circuit that is being charged by a DC voltage source. In this circuit, initially, the capacitor is uncharged. When switch ‘A’ closes, the voltage source (ε) begins charging the capacitor (C) through the resistor (R). Applying Kirchhoff’s Voltage Law results in the equationUsing the definition of capacitance, , where ‘q’ is the charge on the capacitor and ‘VC’ is the voltage across the capacitor, we can solve for the voltage as . Next, using Ohm’s law, the voltage drop across the resistor is . The current through any portion of the circuit is defined as the rate of change of the charge: . Inserting these values into our equation above, we haveThis differential equation can be solved to determine an expression for the charge on the capacitor as a function of time:where is the final charge on the capacitor and is known as the time constant
