Statistics
A researcher wishes to investigate the idea that eating sea saltraises blood pressure less than eating normal table salt. Herandomly selects two groups, each with 13 people. He arranges thatGroup 1 will be on a high sea salt diet for 2 weeks, while Group 2will be on a high table salt diet. He measures their blood pressureafter the two weeks. The mean systolic blood pressure for Group 1,x¯1x¯1, is found to be 126 with a sample standard deviation of 4.0,while for Group 2 the mean, x¯2x¯2 is found to be 116 with a samplestandard deviation of 3.7. Suppose the null hypothesis is thatx¯1=x¯2x¯1=x¯2. Calculate the appropriate statistic to investigatewhether the null hypothesis is likely to be valid.
