The answer is 70/100ths i am pretty sure
Answer:
Test statistic = - 0.851063
- 2.520463
Step-by-step explanation:
H0 : μ ≥ 15
H1 : μ < 15
Sample mean, xbar = 14.5
Sample standard deviation, s = 4.7
Sample size = 64
Teat statistic :
(xbar - μ) ÷ (s/√(n))
(14.5 - 15) ÷ (4.7/√(64))
= - 0.851063
The critical value at α = 0.05
Using the T - distribution :
Degree of freedom, df = 64 - 1 = 63
Tcritical(0.05, 63) = 1.6694
Test statistic - critical value
-0.851063 - 1.6694
= - 2.520463
Hello !

Have a nice day
The unit rate would be found if you made a ratio first of 60:3600. You notice that 60 can go into 3600 by 60 times. This means you get a unit ratio of 1:60. This means that one clownfish cost 60 dollars.
The volume of the figure, using the formula v=bh, equals 8896000. Hope it helps :)
