A 0.01 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is different from 0.5. Assume that sample data consists of 78 girls in 169 births, so the sample statistic of 13 results in a z score that is 1 standard deviation below 0.

According to the National Association of Home Builders, the average cost of building a home in the Northeast is $117.91 per square foot. A random sample of 38 new homes indicated that the mean cost was $123.87 and the standard deviation was $17. Can it be concluded that the mean cost differs from $117.91, using the 0.10 level of significance? Part 1 State the hypotheses and identify the claim with the correct hypothesis. H M - $ 117.91 not claim...
