Answer #1

Not enough information is known to make a conclusion.

Explanation:

For drawing the conclusion regarding the given hypothesis test, we need the values of sample mean for science exam and sample size n. If we know these two values, then we would find the test statistic and p-value; and based on this p-value, we can draw the conclusion regarding the given claim. But due to insufficient data, we cannot draw any conclusion regarding the given hypothesis test.

A sample of 100 students from 9th grades at AA High School can do an average of 11.5 pull-ups (chin-ups) in 30 seconds, with standard deviation of 3.162. The US Department of Health and Human Services suggests 9th grades should do a minimum of 9 pull-ups in 30 seconds. Are the 9th graders at AA High School able to do significantly more pull-ups than the number recommended by the US Department of Health and Human Services? Using this information, answer...

You know that the US population in 1980 had an average IQ score of 100, with a standard deviation of 1.5. The data records information on 900 young males (26 to 36 years old) from NLSY (the National Longitudinal Surveys), surveys conducted in 1980, show an average IQ score of 101. As a result, you suspect that the young males have a slightly higher average IQ than the population. If the standard deviation of the IQ scores for them is...

You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho: μ=100 H1:μ<100 You take a simple random sample of 76 individuals and find the mean IQ score is 95.5, with a standard deviation of 15.1. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known and once with assuming that it is known. Round to three decimal...
