The answer is 0.67, simply show your work subtracting then and you get that number, it’s basic subtraction, only you have to count the decimal points to put them in the correct spot
Given:difference in the mean weight gain is 0.60 gramsstandard deviation of the difference in sample mean is 0.305
68% confidence interval for the population mean difference is a) 0.305
0.60 + 1 * 0.3050.60 + 0.305 = 0.9050.60 - 0.305 = 0.295
95% confidence interval for the population mean difference is c) 0.61
0.60 + 2 * 0.3050.60 + 0.61 = 1.210.60 - 0.61 = -0.01
30%of 68 = 30/100*68= 3*68/10=204/10=20.4
Answer:
Identity property
Step-by-step explanation:
There are 15 ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long
<h3>What is a
line plot?</h3>
A Line plot (dot plots) is a graph or plot that displays on a number line, showing the frequency of each value.
From the image showing the line plot below:
Number of ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long = 5 + 4 + 6 = 15
There are 15 ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long
