Answer:
0.0000454
Step-by-step explanation:
The zeros are not significant since they come before the numbers greater than 0. And I rounded 3 to 4 since the 8 was above 5 so it gets rounded up
Answer:
B. The Interquartile Range (IQR) for the Bulldogs, 20, is less than the IQR for the Tigers, 25
Step-by-step explanation:
The question is asking for a comparison of spread. There are two methods for measuring spread, that are standard deviation and the Interquartile Range. For a skewed box plot like this one you would use the Interquartile Range. The 5 numbers on a box plot are part of the 5 number summary. From left to right the numbers above the box plot are the minimum, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum. To find IQR you just subtract the third quartile (Q3) from the first (Q1). In this case, for the Bulldogs the IQR= 90-70+=20 and for the Tigers IQR=85-60=25.
Answer:
The range is between -20°C and -5°C
Step-by-step explanation:
The relation between C and F is C/5=(F-32)/9
C=(5F-160)/9
For -4°F:
C=(5×-4 - 160)/9=-20°
For 23°F:
C=(5×23-160)/9=-5°
Hope, this helps you.
Answer:
if Cary works at 8 hours per hour, then she will have $440
Step-by-step explanation:
this is, if you are referring to your previous question about Cary making $56 in 7 hours.
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
