Answer:
Step-by-step explanation:
a) Five tests: 85,85,60,62 and 59
Mean = average
= (85+85+60+62+59)/5
= 351/5
Mean = 70.2
Median = middle number (order from least to greatest)
59 , 60, 62, 85, 85
Median = 62
Mode = the ones repeated more often = 85
b) Since mode is the highest score, compare to mean and median.
So mode is the best supports Rolinda's claim that she is doing well in her Spanish class
c) Rolinda's claim is misleading because her first two tests were 85 but then it started decreasing each test after.
