Answer:
The probability of successful long hit is greater than 0.7083
Step-by-step explanation:
Solution
The expected value for long hit is given below
P (successful hit) * 4.2 + P (Unsuccessful hit) *5.4
so,
= P * 4.2 + (1-p) * 5.4
= 5.4 - 1.2p
Now,
If the expected value of long hit is less than that of the short it
Then,
5.4 - 1.2p <4.55
P> (5.4 - 4.55)/1.2
P> 0.7083
Therefore the probability of successful long hit is greater than 0.7083
Note:
Due to my research and findings to this example, the complete question for is attached below, i solved or Question 2(d) only
The average annual temperatures (°F) from 1991 to 2000 for Kentucky were 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.
We have to evaluate the measures of center.
Firstly, we will calculate the mean.
Mean = (Sum of all the observations)/ (Total number of observations)
Mean =
=
= 55.62
Now, we will calculate mode.
Mode is a statistical term that refers to the most frequently occurring number found in a set of numbers.
Consider the data 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.
Mode = 55.6
Now, we will calculate the median.
Firstly, we will arrange in the ascending order.
52.2, 54.4, 54.4,55.1 ,55.6, 55.6, 55.7, 57.3, 57.5, 58.3
Since there are 10 terms.
Median = th observation
Median = 5th observation.
Since, the 5th observation is 55.6.
Therefore, the median is 55.6
