Prof. Gersch knows that the score on a standardized test is perfectly normal with a mean of 200 and a standard deviation of 40. He then takes a random sample of 16 tests. Prof Gersch wants to check the probability that the average of these 16 tests is less than 210. Which of these is equivalent to the probability...

I recommend that you practice using the standard Normal tables to calculate zα/2 and tα/2 . Costs are rising for all kinds of health care. The mean monthly rent at assisted-living facilities was recently reported to have increased 15% over the last five years. A recent random sample of 120 observations reported a sample mean of $3563. Assume that past studies have informed us that the population standard deviation is $650. For this problem, round your answers to 2 digits...

The national mean SAT score is 1435. The standard deviation for all SAT scores is 42.7. A random selection of 31 tests has a(n) mean score of 1425. Can it be concluded that the mean SAT score will be 1435 based on α-level of 0.03? a) Based on reading the problem, how do we know we are working with a hypotheses test (H0andH1H0andH1)? This question has two possible answers. b) Please select the correct normal distribution based on the correct...
