Answer:
Type I error
Step-by-step explanation:
A type I error occurs if the null hypothesis is rejected when it is actually true.
Type I Type II
Reject null when true Fail to reject null when not true
Null hypothesis: ∪ = 30%
Alternative hypothesis: ∪ > 30%
The researchers concluded that more than 30% of first-grade students at this school have entered the concrete operational stage of development and they rejected the null hypothesis.

A type I error has been made because in actuality the null hypothesis was true but was rejected.
Answer:
19
Step-by-step explanation:
11/8 is improper
Proper form would be 1 3/8
Interior angles of a parallelogram have opposite angles identified as "a" and "b".
angles K and I are "a"
angles H and J are "b"
"a" and "b" are supplementary angles, they sum up to 180°.
Angle J is supplementary angle of angle K. Its measure is 143°.
180° - 37° = 143°
Angle H is also 143° while angle I is 37°
