A sample of 70 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.259 and the equation of the regression line is , where x represents height. The mean of the 70 heights is 63.5 in and the mean of 70 pulse rates is 75.1 beats per minute. Find the best predicted pulse rate of a woman who is 67 in tall. Use a significance level of...

A sample of 60 women is obtained, and their heights ( in inches ) and pulse rates ( in beats per minute ) are measured. The linear correlation coefficient is 0.234 and the equation of the regression line is ^y= 17.5 + 0.850x, where x represents height. The mean of the 60 heights is 63.4 in and the mean of the 60 pulse rates is 75.6 beats per minute. Find the best predicted pulse rate of a woman who is...

2. Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear correlation coefficient is 0.849 and the equation of the regression line is ŷ=0.68+0.99x, where x represents the IQ score of the twin born first. Also, the 20 x values have a mean of 100.9 and the 20 y values have a mean of 100.5. What is the best predicted IQ of the twin born second, given that the twin born first has...

A sample of 80 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.218 and the equation of the regression line is ŷ=17.9+0.950x, where x represents height. The mean of the 80 heights is 63.3 in and the mean of the 80 pulse rates is 73.5 beats per minute. Find the best predicted pulse rate of a woman who is 72 in tall. Use a significance level...

1. Police sometimes measure shoe prints at crime scenes so that they can learn something about criminals. Listed below are shoe print lengths, foot lengths, and heights of males. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Based on these results, does it appear that police can use a shoe print length to...

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
