Answer:
And for this case we want to test the following hypothesis:
Null hypothesis:
Alternative hypothesis:
For this case since the lower value of the confidence interval is higher than 42000 we have enough evidence to reject the null hypothesis at the 55 of significance and we can conclude that the true mean is significantly different from 42000
Step-by-step explanation:
The confidence interval for the mean is given by the following formula:
(1)
And for this case the 95% confidence interval is already calculated as:
And for this case we want to test the following hypothesis:
Null hypothesis:
Alternative hypothesis:
For this case since the lower value of the confidence interval is higher than 42000 we have enough evidence to reject the null hypothesis at the 55 of significance and we can conclude that the true mean is significantly different from 42000
Answer:
(a) between 300 grams and 350 grams (b) 95% (c) 5% (d) 83.85%
Step-by-step explanation:
We have that grams and grams. Let's compute the following figures to use the empirical rule
using the image below that was made it with help of the empirical rule we find the next figures
(a) About 68% of organs will be between 300 grams and 350 grams
(b) 95% of organs weights between 275 grams and 375 grams
(c) 5% of organs weights less than 275 grams or more than 375 grams
(d) 83.85% of organs weights between 300 grams and 400 grams
Answer:
1/36
Step-by-step explanation:
P(6,6) = 1/6 x 1/6 = 1/36
Answer:
Expression is; 29 - x = 16
I've attached an image showing the number line
Step-by-step explanation:
We are told that at lunchtime, it was 29 degrees Celsius and that by sunset, the temperature had dropped to 16 degrees Celsius.
Let the drop be x.
Thus;
29 - x = 16
