In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 47.5 km due north. A detector is placed 116 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.

(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

(b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.005

1a. A 747 airplane starts from rest and reaches a takeoff velocity of 78.0 m/s due west in 5.50 s. Assuming a constant acceleration, how far has it traveled before takeoff? Please explain.

b. Use the component method of vector addition to find the resultant of the following two vectors (magnitude and angle): (show the calculations) A=21.0 km, 26 degree south of west B=38.0km, 30 degrees east of south

Rand Medical manufactures lithotripters. Lithotripsy uses shock waves instead of surgery to eliminate kidney stones. Physicians’ Leasing purchased a lithotripter from Rand for $1,540,000 and leased it to Mid-South Urologists Group, Inc., on January 1, 2018. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)
   

Required:
1. How should this lease be classified by Mid-South Urologists Group and by Physicians' Leasing?
2. Prepare appropriate entries for both Mid-South Urologists Group and Physicians' Leasing from the beginning of the lease through the second rental payment on April 1, 2018. Adjusting entries are recorded at the end of each fiscal year (December 31).
3. Assume Mid-South Urologists Group leased the lithotripter directly from the manufacturer, Rand Medical, which produced the machine at a cost of $1.3 million. Prepare appropriate entries for Rand Medical from the beginning of the lease through the second lease payment on April 1, 2018.

Requirement 1:

Requirement 2:

- Prepare appropriate entries for both Mid-South Urologists Group and Physicians' Leasing from the beginning of the lease through the second rental payment on April 1, 2018.

A random sample of leading companies in South Korea gave the following percentage yields based on assets.

Use a calculator to verify that s² ≈ 2.034 for these South Korean companies.

Another random sample of leading companies in Sweden gave the following percentage yields based on assets.

Use a calculator to verify that s² ≈ 0.407 for these Swedish companies.

Test the claim that the population variance of percentage yields on assets for South Korean companies is higher than that for companies in Sweden. Use a 5% level of significance. How could your test conclusion relate to an economist's question regarding volatility of corporate productivity of large companies in South Korea compared with those in Sweden?

(a) What is the level of significance?

State the null and alternate hypotheses.

H_o: σ₁² = σ₂²; H₁: σ₁² > σ₂²H_o: σ₁² > σ₂²; H₁: σ₁² = σ₂²    H_o: σ₂² = σ₁²; H₁: σ₂² > σ₁²H_o: σ₁² = σ₂²; H₁: σ₁² ≠ σ₂²

(b) Find the value of the sample F statistic. (Use 2 decimal places.)


What are the degrees of freedom?

What assumptions are you making about the original distribution?

The populations follow dependent normal distributions. We have random samples from each population.The populations follow independent chi-square distributions. We have random samples from each population.    The populations follow independent normal distributions.The populations follow independent normal distributions. We have random samples from each population.

(c) Find or estimate the P-value of the sample test statistic.

p-value > 0.1000.050 < p-value < 0.100    0.025 < p-value < 0.0500.010 < p-value < 0.0250.001 < p-value < 0.010p-value < 0.001

(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis?

At the α = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant.At the α = 0.05 level, we reject the null hypothesis and conclude the data are statistically significant.    At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.At the α = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant.

(e) Interpret your conclusion in the context of the application.

Fail to reject the null hypothesis, there is sufficient evidence that the variance in percentage yields on assets is greater in the South Korean companies.Reject the null hypothesis, there is insufficient evidence that the variance in percentage yields on assets is greater in the South Korean companies.    Reject the null hypothesis, there is sufficient evidence that the variance in percentage yields on assets is greater in the South Korean companies.Fail to reject the null hypothesis, there is insufficient evidence that the variance in percentage yields on assets is greater in the South Korean companies.
