CROWN-HEELIf a fetus grows % of an inch (4=0.75), in what way can we expect its weightto change?We can expect the weight to decrease by 0.25 ounces.We can expect the weight to decrease by 3 ounces.We can expect the weight to increase by 0.75 ounces.We can expect the weight to increase by 9 ounces. The questions deal with the length (in inches) and weight (in ounces) offetuses from 20 weeks to 42 weeks gestation (23 data points). Lengths offetuses from the top of the head to the heel are estimated by ultrasoundmeasurements. A scatterplot of the data is given below.SLR BASICS CROWN-HEEL SCATTERPLOT14012010080linear model604020111315171921-20Crown-heel length (in.)Weight (oz)

Given scatter plot:From the above scatter plot it can be observed that the variables crown-heel length and weight are positively correlated. That is if crown-heel length increases them weight also increases. Given that If a fetus growth 3 /4 of an inch (3/4=0.75, then expect its weight to change is calculated as follows: It can be seen that 1 unit increase in inch results in 10 unit increases in weight (oz). Thus, if 0.75 inch increases then expected change in weight is 9 ounces. If a fetus growth 3 /4 of an inch (3/4=0.75), then its expect weight change is increases by 9 ounces. Thus, the correct option is, we can expect the weight to increase by 9 ounces.
