Question
A group of laboratory animals is infected with a particular form of bacteria. Their survival times are found to average 32 days, with a standard deviation of 35 days. (a) Think about the distribution of survival times. Do you think that the distribution is relatively mound-shaped, skewed right, or skewed left? Explain. The distribution will probably be mound-shaped. Most animals will survive only around 32 days. The distribution will probably be skewed right. Because the standard deviation is so large, many animals may live well beyond the average survival time. O The distribution will probably be skewed left. Many of the animals will die immediately and not make it to the average survival time. (b) within what limits would you expect at least of the measurements to lie? Using Tchebysheff's Theorem, at least of the measurements will lie between 0 and x days.
