A pet store owner believes that dog owners spend more on average than cat owners on their pets. The owner randomly records the sales of 40 customers that said they only owned dogs and 40 customers that said they only owned cats. What is the correct decision and summary based on the Excel output below? Assume the populations are approximately normally distributed with unequal variances.

t-Test: Two-Sample Assuming Unequal Variances
	Dog	Cat
Mean	57.1695	53.82225
Variance	588.088	573.7205
Observations	40	40
Hypothesized Mean Difference	0
df	78
t Stat	0.6211
P(T<=t) one-tail	0.2682
t Critical one-tail	1.6646
P(T<=t) two-tail	0.5363
t Critical two-tail	1.9908

What is the correct test statistic?
