Strong Covid-19 antibodies typically appear about 2 to 4 weeks after complete vaccination. A researcher took a random sample of 15 Covid-19 patients and, for each of these, determined the number of days after complete vaccination that antibodiesappeared. The following are the number of days for each of the patients in our sample:22, 18, 17, 4, 30, 22, 21, 17, 19, 14, 22, 26, 14, 18, 29It is reasonable to treat these measurements as coming from a normal distribution with unknown mean u and unknown standard deviation oCalculate the sample mean of this data.Calculate the sample variance of this data.Use the R, IQR( ) function to find the interquartile range of this data.
