Below is a sample of the temperatures taken of 50 random students. 95.9, 96.2.96.3.96.5, 96.6, 96.7.96.8, 96.9, 97.1,97.1, 97.1, 97.2, 97.3, 97.3, 97.4, 97.4, 97.4, 97.5, 97.5, 97.5, 97.6, 97.6, 97.6, 97.7,
97.7, 97.8, 97.9, 97.9, 97.9.98.0, 98.0, 98.0, 98.1,98.1, 98.1, 98.1, 98.2, 98.3, 98.4, 98.4, 98.5, 98.6, 98.6, 98.7, 98.9, 98.9, 99.1, 99.3,
99.7, 100.2
A. Create a histogram using ranges 90-95, 95-100. What percent of data falls below 100 degrees? Shade this in.
B. Create a histogram using ranges 95-96, 96-97, 97-98, 98-99, 99-100, 100-101. What percent of data falls below 98 degrees?
Shade this in.
C. Create a histogram using ranges 95.5-96, 96-96.5, 96.5-97, 97-97.5, 97.5-98, 98-98.5, 98.5-99, 99-99.5, 99.5-100, 100-100.5.
What percent of data falls below 97.5 degrees? Shade this in.
D. Sketch a density curve that models this random sample. Shade the lower 50% of the graph. Estimate what temperature is in
the middle of the data.
