Question

question 3 of 5
the data table shows the number of pumpkin seeds that germinate at different temperatures.
effect of temperature on germination of pumpkin seeds

temperature	seeds germinated
20°c	60	63	70	62
24°c	75	87	82	78
28°c	86	84	83	84
32°c	69	64	63	66

what is the median number of seeds that germinate at 24°c?
a. 82
b. 80
c. 78.5
d. 80.5

Explanation:

Step1: List data values

The number of seeds germinated at 24°C are 75, 87, 82, 78.

Step2: Sort data in ascending order

75, 78, 82, 87.

Step3: Calculate median for even - numbered data

Since there are 4 data points (an even number), the median is the average of the two middle - values. The two middle - values are 78 and 82. Median=$\frac{78 + 82}{2}$.

Step4: Compute the result

$\frac{78+82}{2}=\frac{160}{2}=80$.

Answer:

B. 80
