Exаm dаtа were cоllected frоm a representative sample оf 37 students. Their mean score was 90.27 points with a standard deviation of 6.793 points. StatKey was used to construct a bootstrap sampling distribution, which was approximately normal with a standard error of 1.121 Construct a 95% confidence interval to estimate the mean score in the population of all students using the standard error method. Use the following formula, where SE is the standard error: statistic +/- (2 * SE)

This questiоns uses the cоncepts аnd methоds of ASTR 152 Lаb 4 Kepler's Third Lаw. The Star Brahe is a star surrounded by four planets: Brahe a, Brahe b, Brahe c and Brahe d. Astronomical observations of this star system yielded the following data of Orbital periods (in days) for the planets Table 1 Planet Start Date End Date Orbital Period, T (days) Brahe a 12/31/2021 5/17/2022 Brahe b 12/31/2021 10/23/2022 Brahe c 12/31/2021 7/23/2023 Brahe d 12/31/2021 2/11/2025 In addition the following values of the Orbital Radius (in astronomical units, or AU) of each planet was measured: Table 2 Planet Orbital Radius, R (in AU) Orbital Period, T (yrs) R 3 {"version":"1.1","math":"R^3"} T 2 {"version":"1.1","math":"T^2"} Brahe a 0.561 Brahe b 0.823 Brahe c 1.28 Brahe d 2.03 Remember that 1 year = 365 days, unless it is a leap year. Insert completed tables (shorter) or type the answers (if you have issues copying and pasting tables) to the following questions in the answer space below. 1. Determine the orbital periods of the four planets (Brahe a, Brahe b, Brahe c, Brahe d) in days and complete Table 1 and attach in the answer space. You may also type the planet name followed by the number of days. For example if this was done for our solar system, a. Mercury = 88 days, Venus = 225 days, Earth = 365 days, etc. 2. Now complete Table 2 (which you must attach in answer space) in which there are two steps: a. Determine the orbital periods of the four planets (Brahe a, Brahe b, Brahe c, Brahe d) in years and enter in your Table 2 to be attached. If you cannot paste this table, type the planet name followed by the number of days. for example if this was done for our solar system, b. Mercury = 0.241 years, Venus = 0.615 years, Earth = 1.0 years, etc. b. Compute R^3 and T^2 and enter into your Table 2. Attach Table 2 into the answer space or type the answers as you did in part (a) above. 3. Using the orbital periods (in years) and the orbital radius (in AU), determine the mass M (in units of solar masses) of the star Brahe for each of the planet. Type out your results. For example if this was done for our solar system, c. Mercury gives 0.98, Venus gives 1.01, Earth gives 1.00, ETC. d. Using the results from part(c), determine the average mass M¯ of the star Brahe and type the result in the answer space.
