1. Use the Pima.tr data set to evaluate the hypothesis that the population mean of diastolic blood pressure for Pima Indian women is not 70. ( please solve using R studio) R code. The Pima.tr is included in the R software. ( try to add "MASS "or "library")

1. Suppose that the population mean of systolic blood pressure in the US is 115. We hypothesize mean systolic blood pressure is lower than 115 among people who consume a small amount (e. g., around 3.5 ounces) of dark chocolate every day. Assume that systolic blood pressure, X, in this population has a N01,, 02) distribution. To evaluate our hypothesis, we randomly selected 100 people, who include a small amount of dark chocolate in their daily diet, and measured their blood pressure. Ifthe sample mean is J? = 111 and the sample variance is s = 32, can we reject the null hypothesis at 0.1 condence level? 2. Use the Pima . tr data set to evaluate the hypothesis that the population mean of diastolic blood pressure for Pima Indian women is not 70
