Answer:
The modal class is 1 - 10
Step-by-step explanation:
Given
See attachment for frequency distribution table
Required
Determine the modal class
To determine the modal class, we simply look for the class with the highest frequency.
In the given frequency distribution table, class 1 - 10 has the highest frequency of 21.
<em>Hence, the modal class is 1 - 10</em>

The accuracy in the research done by university is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.
Given sample size of 58205 and proportion of people donated 576. Cutoff is 0.5.
Probability is the chance of happening an event among all the events possible. It lies between 0 and 1.
TP=total people donated in sample, TN=total number of people,FP=donation,FN=No donation
Accuracy is calculated as under:
=(TP+TN)/(TP+TN+FP+FN)
=(268+23439)/(238+23439+5375+20)
=23707/29102
=0.81
Accuracy=0.81
Sensitivity is calculated as under:
=TP/(TP+FN)
=268/(268+20)
=268/288
=0.93
Precision is calculated as under:
=TP/(TP+FP)
=268/(268+5375)
=268/5643
=0.047
Their values are the probabilities in itself.
Hence accuracy is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Answer:
3 hours
Step-by-step explanation:
She has 224-59=165 miles left to drive. Since her speed is 55 mph, time is equal to distance/speed, so 165mi/55mph = 3 hours
