I need help doing the one sided/single tailed z test both by hand and the commands in r studio if you could please show me. My null hypothesis is that children do not have a higher resting heart rate than adults. While the Alternative Hypothesis is that children have a higher resting heart rate than adults. There is a sample of 100 participants, which are divided into 50 adults, and 50 children. Please show me how to do the problems step by step by both r studio and hand computation, along with what the results mean. I will input my data below.
