Question

A horse trainer teaches horses to jump by using two methods of instruction. Horses being taught by method A have a lead horse that accompanies each jump. Horses being taught by method B have no lead horse. The table shows the number of training sessions required before each horse performed the jumps properly.

Method A	43	23	49	44	39	22
Method B	27	25	48	31	37	46

Method A	47	26	29	33	36	42
Method B	28	45	41	34	51

Use a rank-sum test with a 10% level of significance to test the claim that there is no difference between the training sessions distributions. State the conclusion of the test and interpret your results with a 10% level of significance.

	a.	Since the P-value is greater than the level of significance, the data are statistically significant. Based on this, we reject the null hypothesis.
	b.	Since the P-value is greater than the level of significance, the data are statistically significant. Based on this, we fail to reject the null hypothesis.
	c.	Since the P-value is less than the level of significance, the data are statistically significant. Based on this, we reject the null hypothesis.
	d.	Since the P-value is less than the level of significance, the data are statistically insignificant. Based on this, we fail to reject the null hypothesis.
	e.	Since the P-value is greater than the level of significance, the data are statistically insignificant. Based on this, we fail to reject the null hypothesis.
