Answer:
a) 0.1091
b) 0.9994
c) 0.5886
Step-by-step explanation:
X = the number of fish out of 20 that die after 24 hours
x = 0, 1, 2, . . . , 20
X~ Binomial (n= 20, p =0.20)
P(14 survive) = P(X = 6)
= =0.1091
Similarly we can find out
P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994
P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
Answer:
The interquartile range of the data set is: 11 years
Step-by-step explanation:
The ages of a group of state governors at their inaugurations are listed below :
50,38,45,47,53,54,57,40,57,64,58,52
On arranging our data in increasing order i.e. in ascending order we have:
38 40 45 47 50 52 53 54 57 57 58 64
we divide our data into quartiles.
- The median of the data i.e.
is the middle value of the set.
Here in thus data the middle value will lie between 52 and 53.
Hence, the median is
- the lower data is given as:
38 40 45 47 50 52
Hence will lie between 45 and 47 which is 46.
Hence,
- the upper data is given as:
53 54 57 57 58 64
Hence, will lie between 57 and 57 which is 57.
Hence,
Hence, the interquartile range of the data is given as:
.
Hence, the interquartile range is 11 years.
