A group of researchers wanted to determine if the mean HDL of male patients is less than female patients. HDL from one hundred patients were collected and results are as follows: Gender n 28 72 Male Female Mean ± SD 1.1318±0.16191 1.2828±0.11039 Do these results show sufficient evidence that the mean HDL of male patients is less than female patients? Test at 5% level of significance. Let the critical value be t = 1.686 if t> 0 or t = -1.686 if t < 0. Which of the following is the correct conclusion? O There is no sufficient evidence that the mean HDL of male patients is less than female patients. O There is sufficient evidence that the mean HDL of male patients is less than female patients. O There is no sufficient evidence that the mean HDL of female patients is less than male patients. O There is sufficient evidence that the mean HDL of male patients is not equal to the female patients.

Question
A group of researchers wanted to determine if the mean HDL of male patients is less than female patients. HDL from one hundred patients were collected and results are as follows: Mean±SD Gender n 28 72 Male Female 1.1318 +0.16191 1.2828 +0.11039 Do these results show sufficient evidence that the mean HDL of male patients is less than female patients? Test at 5% level of significance. S Let the critical value be t = 1.686 if t > 0 or t = - 1.686 if t ≤ 0. Which of the following is the correct conclusion? O There is no sufficient evidence that the mean HDL of male patients is less than female patients. O There is sufficient evidence that the mean HDL of male patients is less than female patients. O There is no sufficient evidence that the mean HDL of female patients is less than male patients. O There is sufficient evidence that the mean HDL of male patients is not equal to the female patients.
