A current of 5 mA flows through a 2 mm inner-diameter glass tube filled with 1.0 mol dm-3 NaCl(aq) solution in the anode compartment in addition to a CH3COONa (aq) solution in the cathode compartment. The boundary created between the two solutions moves 6.05 mm towards the anode in 10 minutes. Calculate the transport number of the chloride ion in the solution.

According to the document Consumer Expenditures, a publication of the U.S. Bureau of Labor Statistics, the average consumer unit spent $1749 on apparel and services in 2002. That same year, 25 consumer units in the Northeast had the following normally distributed annual expenditures, in dollars, on apparel and services. At the 5% significance level, do the data provide sufficient evidence to conclude that the 2002 mean annual expenditure on apparel and services for consumer units in the Northeast differed from the national mean of $1749? (Note: The sample mean and sample standard deviation of the data are $1935.76 and $350.90, respectively.)  Check the assumptions  Hypotheses  Sample mean: Sample Std. dev: Sample size: Significance level:  P-value = Conclusion: Since P-value is ___________ than the significant level, _________, we ____________ null hypothesis.
