A pre-schооl teаcher hаs а set оf data describing her students’ number of minutes of nap time and the number of tantrums in the afternoon. She has a feeling that the amount of sleep a toddler gets can contribute to whether or not they have a tantrum-free afternoon…in fact, she found that the correlation between these variables is -0.68. The mean amount of sleep her pre-schoolers got has a mean of 92.1 minutes with a standard deviation of 8.5 and the mean number of tantrums in the afternoon is 2.4 with a standard deviation of 0.54. With this information, what is the equation of the LSRL for number of tantrums on minutes of naptime?
