REGION ID

1= Crete
2=Southern Aegean Islands
3=Ionian Islands

George who is the General Director of the Research Institute for Tourism in Greece, believes that the percentage composition of 5 Stars hotels is not the same in Crete and elsewhere (Southern Aegean Islands and Ionian Islands). In order to test this statement, create two additional binary variables as follows:
5STARS: Yes (Code 1) when STARS = 5; No (Code 0) when STARS ≠ 5.
CRETE: Yes (Code 1) when Region_ID = 1; No (Code 0) when Region_ID ≠ 1.
3.1 State the null and the alternative hypotheses.
3.2 Test the null hypothesis at α = 5%.
3.3 What is your conclusion?
3.4 Let π1 denote the population proportion of 5 stars hotels in Crete and π2 the population proportion of 5 stars hotels elsewhere. Set up a symmetric 95% confidence interval estimate of the difference (π1 - π2). What is your main conclusion?

The Gaia satellite will measure parallaxes with an accuracy of 2 × 10−5 arcsec for stars with V < 15. (a) What is the distance d of an M5 I supergiant with log(L/Lʘ) = 5.50 and BC = −3.70 that has V = 12, if the effect of interstellar extinction is ignored? (b) What is the relative distance accuracy σ(d)/d of such a star? (c) Assuming that Teff is known, what is the relative accuracy in radius σ(R)/R?
