29035 is to the right of 0.
-1349 is to the left of 0.
so, the distance between them:
29035 - (-1349) = 29035+1349 = 30384

Answer: mean=26 , median=24
Step-by-step explanation:
Mean=Sum of all values/number of values
mean= 30+39+24+ 19+18/5
= 130/5
mean=26
Median
arrange data in order
18,19,24,20,39
In the case of ungrouped odd-numbered data, the number that divided data into 2 equal parts is called the median.
so median=24
Answer: D
H0: μ=522
H1: μ>522
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
So, for this case;
The null hypothesis is that the mean score equals to 522
H0: μ=522
The alternative hypothesis is that the mean score is greater than 522.
H1: μ>522
