6a - 18. If you need an explanation let me know. Hope this helps.
(5.2,7.6)
mean=6.4
standard deviation=0.6
we have to find the range in which at least 75% of the data will reside
1-1/k²=0.75
1/k²=1-0.75
1/k²=0.25
k²=1/0.25=4
k=2
so, k=2
The range of values can be computed as mean±k(standard deviation).
Thus, the range in which at least 75% of the data will reside is
(mean-k(standard deviation), mean+ k(standard deviation))
(6.4-2(0.6),6.4+2(0.6)
(6.4-1.2,6.4+1.2)
(5.2,7.6)
