find the area under the t curve to the right of t = -1.86. let n = 30. (round to four decimal places as needed)\na = \ni dont know\n2 attempts

Answer

Explanation:

Step1: Calculate degrees of freedom

Degrees of freedom $df = n - 1 = 30 - 1 = 29$

Step2: Use t-table or calculator logic

For $t=-1.86$ and $df=29$, the area to the left of $t=-1.86$ is approximately 0.0375. The total area under the t-curve is 1, so the area to the right is $1 - 0.0375$. <Expression> $1 - 0.0375 = 0.9625$ </Expression>

Answer:

0.9625
