Step-by-step explanation:
Given: The mean number of hours per day spent watching television, according to a national survey, is 3.5 hours, with a standard deviation of two hours.
To Find: If each time was increased by one hour, what would be the new mean and standard deviation.
Solution:
let the total numbers entries of hours in survey be = 
each entry in survey be = 
mean of survey is =
=

standard deviation is =
=

if each entry in survey is increased by one hour then,
each new entry in survey is = 
the new mean is
= 


+
=
+ 1=

now,
standard deviation is


putting values,

=
=2
new mean and standard deviation are
and
