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.

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...
