The square number is 4 hence The answer is 4
No, it is an exponential equation. It has an exponent.
Answer:
Step-by-step explanation:
<u>Total frequencies:</u>
Median group is the containing the middle - 25th and 26th frequencies. This is the 11-15 interval.
<u>Estimated median formula:</u>
- Estimated Median = L + ((n/2) − B)/G* w, where
- L - lower class boundary of the group containing the median = 10.5
- n - total number of values = 50
- B - cumulative frequency of the groups before the median group = 6 + 15 = 21
- G - frequency of the median group = 20
- w - group width = 5
<u>Substitute values and work out the number:</u>
- Estimated Median = 10.5 + (50/2 - 21)/20*5 = 11.5
