Todd M asked:
The present method requires 42.3 minutes, on the average, to assemble a cart. The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?

For one tailed 10 level test stat exceeds the critical value hence we can reject h0 423 ha 423 27 sqrt24 3085 from t23 tables for one tailed 10 level test t_crit 1319460 again out test stat exceeds the critical value hence we can reject h0 423 ha 423 27 sqrt24 3085.

The critical value hence we can reject h0 new method is faster.
