Note: Reference the Fundamental constants table for additional information. Part 1 of 2 $5.09 \times 10^{21}$ formula units of FeCl$_3$ = mol of ions Part 2 of 2 $9.80 \times 10^{22}$ formula units of NiCl$_2$ = mol of ions
Important: This question continues from the previous question. A random sample of 50 high school students were asked how long it took for them to get to school. The sample mean was 16.2 minutes and the sample standard deviation was 12.3 minutes. Construct a 95% confidence interval for the length of time it takes high school students to get to school. Remember to include the proper unit for both the lower and upper values. The lower value of the confidence interval is The upper value of the confidence interval is For the values above, rounding to 1 decimal places.
