"A researcher analyzed the results of an experiment and found that the obtained t-value (on a t-test of independent means) was 1.29, with a total of 25 children in group 1 and 30 children in group 2. Use a table of critical values and discuss whether the null hypothesis can or cannot be rejected. (Hint: Use Table 8.6 and 30 as the degree of freedom to support your decision.)"
Which of the following describes a basic reliability test? measure twice and compare the results compute the mean of results and compare to hypothesis have a second observer record the same data divide the mean of results by the standard deviation
3. A student measured Cl- in a sample using ISE and obtained the following results for Cl- in a sample from 10 replicates: Mean - 40.22 ppm standard deviation 3.12. The true value was 39.10. Is there a significant difference between the experimental value and true value? -1,-1)+ Sz4n2-11 n, the 5 .nswer one of the following two questions:
1. Based upon the results obtained in your experiment, formulate a mechanism that will account for all products observed. What rule does the mix follow? 2. One student refluxed the reaction mixture for 20 minutes instead of just distilling over the product as it is formed. The resultant product was approximately 100% 1-methylcyclohexene. Explain why this happened. 3. The GC depicted in Fig. 1 was obtained on analysis of the dehydration of the alcohol below. Interpret the GC data in...
