- Ivan je naučio 15 pitanja od 20, tako da je broj pitanja koja nije naučio 20 - 15 = 5 .
- Ukupan broj pitanja je 20.
- Vjerojatnost da je Ivan dobio pitanje koje nije naučio iznosi \frac{5}{20} .
- Jednostavnim deljenjem dobijamo vjerojatnost: \frac{5}{20} = \frac{1}{4} .

Odgovor je: \frac{1}{4} .

The average weekly earnings in the leisure and hospitality industry group for a re‐ cent year was $273. A random sample of 40 workers showed weekly average ear‐ nings of $285 with the population standard deviation equal to 58. At the 0.05 level of significance can it be concluded that the mean differs from $273? Find a 95% con‐ fidence interval for the weekly earnings and show that it supports the results of the hypothesis test.
