Suppose IQ scores were obtained for

randomly selected sets of

couples.

The

pairs of measurements yield

x=102.2,

y=100.8,

r=0.854,

P-value=0.000,

and

y=24.13+0.75x,

where x represents the IQ score of the

wife.

Find the best predicted value of

given that the

wife

has an IQ of

95?

Use a significance level of 0.05.

Click the icon to view the critical values of the Pearson correlation coefficient r.

The best predicted value of

nothing.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.

Listed in the data table are IQ scores for a random sample of subjects with medium lead levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviation’s are equal. Use a 0.05 significance level to test the claim that the mean IQ scores for subjects with medium lead levels is higher than the mean for subjects with high lead levels.
