measurements of people are built by giving them wood and asking them to build the tallest tower humanly possible. 1 of those expermiemnds was repeated a month later, with the times (in seconds) and five pairs of children’s completion times are listed below.
Test claim that there is a difference in times between two trials. (a) At α = 1%, use classical approach and conclude (b) Use the P-value approach to conclude it.
1st Trial (A) 35 28 29 26 29
2nd Trial (B)33 27 27 27 23 .
estimate of standard error =8
P-value method- Using the t-distribution, we find the p-value is equal to 0.3899 for two-tailed test. 0.3899> sign level a/2=0.005, we fail to reject. So there's notsufficient evidence to conclude a big difference on the times between the 2 trials
