University officials say that at least 70% of the voting student population supports a fee increase. If the 95% confidence interval estimating the proportion of students supporting the fee increase is [0.75, 0.85], what conclusion can be drawn?

• Since this was not based on the population, no conclusion can be drawn.

• The interval estimate is above 70%, so infer that it will be supported.

• Seventy percent is not in the interval, so assume it will not be supported.

• Seventy percent is not in the interval, so another sample is needed.

A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. What is the alternate hypothesis?

• H₁: 6.6

• H₁: = 6.6

• H₁: > 7.6

• H₁: 6.6
