Answer: 0.0016
Step-by-step explanation:
Given the following :
Population mean(m) = 196
Population Standard deviation (sd) = 32
Number of sample (n) = 18
Sample mean (x) = Total weight of sample / number of samples = 3928 / 18 = 218.2
Obtaining the test statistic (z) :
Z = [(x - m) / (sd/√n)]
Z = [(218.2 - 196) / (32/√18)]
Z = [(22.2 / 7.5424723)]
Z = 2.943
Hence,
P(Z > 2.94) = 1 - P(Z < 2.94)
= 1 - 0.9984
= 0.0016

Answer:
Step-by-step explanation:
Since the height of each bounce is 3/4 of its last peak height we can use a geometric sequence to find the bounce height for any number of bounces.
h=12(3/4)^b
h(5)=12(3/4)^5
h(5)=2.85m
