Question

for how many days was the temperature recorded? frequency (number of days) degrees fahrenheit 40 - 44 45 - 49 50 - 54 55 - 59 60 - 64 65 - 69

Explanation:

Step1: Identify the task

We need to sum the frequencies in the histogram to find total number of days.

Step2: Read frequencies

Let's assume the frequencies for the intervals 40 - 44, 45 - 49, 50 - 54, 55 - 59, 60 - 64, 65 - 69 are \(f_1,f_2,f_3,f_4,f_5,f_6\) respectively. Read these values from the histogram.

Step3: Calculate total days

The total number of days \(T=f_1 + f_2+f_3+f_4+f_5+f_6\).

Since the values of the frequencies are not clearly visible in the provided image, if we assume the frequencies are \(f_1 = 3\), \(f_2= 5\), \(f_3 = 7\), \(f_4=4\), \(f_5 = 2\), \(f_6=1\) (these are just example values for illustration purposes as the actual values are not clear):
\[T=3 + 5+7+4+2+1=22\]

Answer:

The total number of days (assuming example - values) is 22. You need to read the actual frequencies from the histogram to get the correct answer.
