As a part of her studies, Floretta gathered data on the lifespan of 24 fruit flies. She works through the testing procedure:

• H0:=32; Ha:<32
• =0.02
• The test statistic is t0=x0sn=1.956.
• The critical value is t0.02=2.177.

At the 2% significance level, does the data provide sufficient evidence to conclude that the mean lifespan of fruit flies is less than 32 days?

Select the correct answer below:

1. We should reject the null hypothesis because t0
2. We should not reject the null hypothesis because t0
3. We should reject the null hypothesis because t0>t. So, at the 2% significance level, the data provide sufficient evidence to conclude that the average lifespan of fruit flies is less than 32 days.
4. We should not reject the null hypothesis because t0>t. So, at the 2% significance level, the data do not provide sufficient evidence to conclude that the average lifespan of fruit flies is less than 32 days.
