Animal researchers studying cows and horses conducted a two-sample t-test for a difference in means to investigate whther grazing cows eat more grass, on average, than grazing horses. All conditions for inference were met, and the test produced a test statistic of t=1.664 and a p-value of 0.0487. Which of the following is a correct interpretation of the p-value?

The actual p-value should be more than 0.05 to apply the null hypothesis. Here, the null hypothesis is not applicable.

Given information:

Animal researchers studying cows and horses conducted a two-sample t-test for a difference in means to investigate whther grazing cows eat more grass, on average, than grazing horses.

Test statistic says that t=1.664.

p-value is 0.0487.

Now, the null hypothesis is applied when the value of p-value is more than 0.05.

So, here there the null hypothesis is ignored as actual p value is less than 0.05.

Therefore, the actual p-value should be more than 0.05 to apply the null hypothesis. Here, the null hypothesis is not applicable.
