Solutions

Expert Solution

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 0.83 . According to guidelines specified by Cohen, this corresponds to a large effect size.

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 0.33 . According to guidelines specified by Cohen, this corresponds to a small effect size.

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 1. According to guidelines specified by Cohen, this corresponds to a large effect size.

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 2.67 . According to guidelines specified by Cohen, this corresponds to a large effect size..

.

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 0.17 According to guidelines specified by Cohen, this corresponds to a small effect size...

Therefore, the following effect size (Cohen's d) is computed as:

Interpretation: The effect size obtained is d = 1.17. According to guidelines specified by Cohen, this corresponds to a large effect size.

Historically, weights of polar bears have been known to be Normally Distributed with a population mean of approx. 550 kg and a standard deviation of about 110 kg. Researchers are studying the effect of climate change on these animals; their hypothesis is that, because of the diminishing size of their feeding habitats, the average polar bear will be smaller than in the past. 1.) What is the probability that a randomly selected polar bear would weigh less than 480 kg?...
