Answer:
0.288 < p < 0.338
Step-by-step explanation:
We have 2331 adults polled and 730 said they believe in UFOs. We are to construct a 99% confidence interval for the population proportion. We are told to round to 3 decimal places as needed.
We need to find p-hat and q-hat
p-hat = 730/2331 = 0.313
q-hat = 1 - p-hat = 1 - 0.313 = 0.687
Since the sample size is greater than 30, we use a z-value for 99% confidence, which is 2.575
See attached photo for the construction of the confidence interval
Answer:
Use the regression calculator to compare the teams’ number of runs with their number of wins.
A 2-column table with 9 rows. Column 1 is labeled R with entries 808, 768, 655, 684, 637, 619, 613, 609, 563. Column 2 is labeled W with entries 93, 94, 66, 81, 86, 75, 61, 69, 55.
What is the y-intercept of the trend line, to the nearest hundredth?
Step-by-step explanation:
Answer:
B=10
Step-by-step explanation:
worked it out on a graph on the internet
what do you need help with?
Slope intercept form is: y=mx+b
So you take the first equation: 2x-3y=6 and you subtract the 2x from both sides and get: -3y= 2x+6
Then you take that equation: -3y= 2x+6 and divide -3 from both sides and get: y= -2/3x -2
So the equation 2x-3y=6 in slope intercept from is
y = -2/3x -2
Can you do the next one your self based on the one i did...?
(Scroll and check ⬇️ )
Here ya go ;)
5x + 2y = 3 okay same steps as above you want to get the x on the other side so you subtract the 5x from both sides and get:
2y = 5x + 3
Then you want to get the y by its self so you divide the 2 from both sides so you get:
y = 5/2x +2/3
Now idk if your allowed to leave it like that (based on your teacher's preferance really) but if not you can simplfy your fractions and get:
y = 2.5x + 0.66
( i would leave the 2/3 and just leave it as y = 2.5x + 2/3 ) but you do you and i hope that helped you :)
