According to researchers at Stanford Medical School (as cited in Medical Self Care), the ideal weight for a woman is found by multiplying her height in inches by 3.5 and subtracting 108. The ideal weight for a man is found by multiplying his height in inches by 4 and subtracting 128. Using PHP and HTML 5, design and build a web page that calculates the ideal weight given the person’s gender and height. The user selects the gender from a drop down list and enters the height in a text box. Your PHP script should read all the input and calculate and display the ideal weight.

Stanford University medical researchers conducted a study on the correlation between the use of fertility drugs and ovarian cancer. Their study, published in the American Journal of Epidemiology, concludes that the use of the fertility drugs, Pergonal and Serophene, may increase the risk of ovarian cancer by three times. The lead author of the studies, Professor Alice Whittemore, stated, "Our finding in regard to fertility drugs is by no means certain. It is based on very small numbers and is...

Researchers believe that learning through video imitation will improve self-care skills. For 6 months the researchers worked with mentally impaired individuals in which half were taught self-care skills through video imitation and the other half through physical guidance. At the end of the 6 months, individuals were asked to independently perform the self-care task and were rated on the level of required assistance where a higher score indicates more assistance. What can be concluded with an α of 0.05? The...

Medical researchers have noted that adolescent females are much more likely to deliver low-birth-weight babies than are adult females. Because low-birth-weight babies have a higher mortality rate, a number of studies have examined the relationship between birth weight and mother's age. One such study is described in the article "Body Size and Intelligence in 6-Year-Olds: Are Offspring of Teenage Mothers at Risk?"† The following data on maternal age (in years) and birth weight of baby (in grams) are consistent with...
