Step-by-step explanation:
given that the following data represent the discrete probability distribution for the number of stars that reviewers have a first edition statistics reference book.
Stars 5 4 3 2 1
Probability 25% 35% 20% 10% 10%
H0: Second edition is as per the above probabilities
Ha: atleast one is different from the above probability
(two tailed chi square test)
Alpha = 0.025
Assuming H0 to be true we calculate expected frequencies for total 80
chi square calculatons are shown below
df = 4
5 4 3 2 1 Total
Observed 28 28 13 6 5 80
Expected 20 28 16 8 8 80
chi square
(O_E)^2/E 3.2 0 0.5625 0.5 1.125 5.3875
p value =0.1455
Since p value >0.025, we accept H0
The expected requency of three-star reviews is ________.16
The sun rises directly east and sets directly west regardless of the latitude, thus making the azimuth angles 90° at sunrise and 270° at sunset. The reason is the tilt of Earth's axis of rotation with respect to the orbital plane.. l hope it helped :)
