Part A: 5 out 25 lobsters have dangerous levels of mercury
Part B: the 95% confidence interval is given by (4.45, 5.65)
since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064
Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)
For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65

Answer:
The rate of change is "-3". Which means the rate at which the tractor uses fuel.
Step-by-step explanation:
The equation describes a line and any line follows the equation:
y = m*x + c
Where "m" is the rate of change and "c" is the shift on the line. Comparing the equation for the fuel and the equation from the line, the rate of change must be "-3". The rate of change in this context describes the speed at which the tractor uses fuel, at a rate of 3 gallons per hour.
Answer:
The total amount she will pay after taxes is $339.58
Step-by-step explanation:
The Total cost of the speaker plus tax = $349
The tax rate applied = 2.7%
Tax payable = $349 * 2.7% = $9.423
The tax amount on the speaker is Tricia = $9.423
Thus, the total amount she will pay after taxes (i.e. paying $9.423) for purchase of the Speaker will be = $349 - $9.423 = $339.58.
The original price of the speaker excluding tax is $339.58.
