Answer:

Step-by-step explanation:
H0: µ1 – µ2 = 0
HA: µ1 – µ2 ≠ 0
We have given,
The population variances are not known and cannot be assumed equal.
The test statistic for the test is

Where,
 = sample meaan of population 1
 = sample meaan of population 1
 = sample mean of population 2
 = sample mean of population 2
 = sample size of population 1
 = sample size of population 1
 = sample size of population 2
 = sample size of population 2
Therefore, this is the test 

 
        
             
        
        
        
Tiger shark:
 2240 miles in 28 days = 80 miles/day
GW shark:
 2368 miles in 32 days = 74 miles/day
80 miles/day x 32 days = 2560 miles the Tiger shark would have traveled
2560-2368 = 192
If the tiger shark had traveled at the same rate for 32 days, the tiger shark would have traveled 192 miles more than the great white shark
        
             
        
        
        
Answer:
The circumference of a circle with a latitude of 40 degrees is 251.33
 
        
             
        
        
        
73.94 X .33 = 24.40 thats how much the markup (or profit is)
73.94 + 24.40 = 98.34 thats how much they sold it for.
