As a part of her studies, Floretta gathered data on the lifespan of 24 fruit flies. She works through the testing procedure:H0:μ=32; Ha:μ<32α=0.02The test statistic is t0=x¯−μ0sn√=−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:We should reject the null hypothesis because t0<tα.

Question

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

H0:μ=32; Ha:μ<32
α=0.02
The test statistic is t0=x¯−μ0sn√=−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:

We should reject the null hypothesis because t0<tα. 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.
We should not reject the null hypothesis because t0<tα. 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.
We should reject the null hypothesis because t0>tα. 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.
We should not reject the null hypothesis because t0>tα. 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.
