spin [16.1K]

Answer: a) critical value = 0.0853, b) we reject the null hypothesis.

Step-by-step explanation:

Since we have given that

z = -1.37

And the hypothesis are given below:

$H_0:p=\dfrac{1}{4}=0.25\\\\H_1:p\neq 0.25$

Since α = 0.01

since critical value = 0.0853

As we can see that 0.853 < 0.25.

so, we reject the null hypothesis.

Hence, a) critical value = 0.0853, b) we reject the null hypothesis.

You asked your classmates to name their favorite type of music. You found that 12 students like rock, 8 like rap, 6 like R&B

SSSSS [86.1K]

First we should write the total numbers:
12+8+6+4=30
then we should divide the number 30 by 360(because the pie chart is 360 degrees):
$360 \div 30 = 12$

now we should multiply 12(the number of students who likes rock) by 12
$12 \times 12 = 144$
the answer is 144 degrees
