Answer question 7.2.11. stepwise please 

7.2.11 Like hurricanes and earthquakes, geomagnetic storms are
natural hazards with possible severe impact on the earth. Severe
storms can cause communication and utility breakdowns, lead-
ing to possible blackouts. The National Oceanic and Atmospheric
Administration beams electron and proton flux data in various
energy ranges to various stations on the earth to help forecast pos-
sible disturbances. The following are 25 readings of proton flux
in the 47-68 KEV range (units are in p/(cm2-sec-ster-MeV)) on
the evening of December 28, 2011:
2310 2320 2010 10800 2190 3360 5640 2540 3360 11800 2010
3430 10600 7370 2160 3200 2020 2850 3500 10200 8550 9500
2260 7730 2250
a. Find a point estimate of the mean proton flux in this time
period.
b. Find a point estimate of the standard deviation of the pro-
ton flux in this time period.
c. Find an estimate of the standard error of the estimate in
part (a).
d. Find a point estimate for the median proton flux in this
time period.
e. Find a point estimate for the proportion of readings that
are less than 5000 p/(cm2-sec-ster-MeV).
