Here is a sample of temperature measurements (in units of ∘C^{\(\circ\)}\(\text{C}\)) taken from laboratory samples after a heating process: {22,25,28,32}\(\left\[\lbrace\)22,25,28,32\(\right\]\rbrace\). The ten bootstrap samples (based on sampling with replacement) are: {22,25,28,32}\(\left\[\lbrace\)22,25,28,32\(\right\]\rbrace\), {28,32,25,28}\(\left\[\lbrace\)28,32,25,28\(\right\]\rbrace\), {25,22,32,28}\(\left\[\lbrace\)25,22,32,28\(\right\]\rbrace\), {22,28,32,25}\(\left\[\lbrace\)22,28,32,25\(\right\]\rbrace\), {28,25,25,32}\(\left\[\lbrace\)28,25,25,32\(\right\]\rbrace\), {32,28,22,28}\(\left\[\lbrace\)32,28,22,28\(\right\]\rbrace\), {25,32,28,22}\(\left\[\lbrace\)25,32,28,22\(\right\]\rbrace\), {28,22,28,25}\(\left\[\lbrace\)28,22,28,25\(\right\]\rbrace\), {32,25,28,22}\(\left\[\lbrace\)32,25,28,22\(\right\]\rbrace\), {28,32,22,25}\(\left\[\lbrace\)28,32,22,25\(\right\]\rbrace\). Using only these ten bootstrap samples, construct an 80%80\% confidence interval estimate for the true mean temperature of the laboratory samples.
