Answer:

H0 : μ = 24

H1 : μ < 24

My grade is 92 if an assignment is worth 40% of my grade what will my grade be if I got a 0, 25, and a 50?
Vadim26 [7]
<span>
If you get a 0 on your assignment, your grade will be (92 * 0.6) + (0 * 0.4), which will give you a final grade of 55.2%

If you get a 25 on your assignment, your grade will be (92 * 0.6) + (25 * 0.4), which will give you a final grade of 65.2%

If you get a 50 on your assignment, your grade will be (92 * 0.6) + (50 * 0.4), which will give you a final grade of 75.2%

If you get a 75 on your assignment, your grade will be (92 * 0.6) + (75 * 0.4), which will give you a final grade of 85.2%

If you get a 100 on your assignment, your grade will be (92 * 0.6) + (100 * 0.4), which will give you a final grade of 95.2%</span>
