Answer:
1) a. Move farther into the tails
2) a. Decreases
Step-by-step explanation:
Hello!
1)
Let's say for example that you are making a confidence interval for the mean, using the Z-distribution:
X[bar] ± 
* 
Leaving all other terms constant, this are the Z-values for three different confidence levels:
90% 
95% 
99% 
Semiamplitude of the interval is
d= *
Then if you increase the confidence level, the value of Z increases and so does the semiamplitude and amplitude of the interval:
↑d= ↑ *
They have a direct relationship.
So if you change α: 0.05 to α: 0.01, then the confidence level 1-α increases from 0.95 to 0.99, and the boundaries move farther into the tails.
2)
The significance level of a hypothesis test is the probability of committing a Type I error.
If you decrease the level from 5% to 1%, then logically, the probability decreases.
I hope this helps!
1. You have the following information:
<span>
- Maria has 8 1/2 quarts of soil.
- Each pot requires 3/4 quart of soil.
</span>
2. Keeping this on mind, you can convert the mixed number 8 1/2 and the fracion 3/4 to decimals, as below:
8 1/2=8.5 quarts
3/4=0.75 quarts
3. Therefore, you have:
1 pot-----0.75 quarts
x-----8.5 quarts
x=(8.5x1)/0.75
x=11 pots
<span>
For how many pots does Maria have enough soil?
</span>
The answer is: 11 pots
Answer The Mexican tribe where children of FOUR are fed mind-bending magic mushrooms by witchdoctors in 'surviving childhood' rituals
The hallucinogenic mushrooms grow in the hills of Mexico's Oaxaca state
Shamans give them to young children to celebrate their 'surviving infancy'
Alejandro Garces, three, will be fed the mushrooms by his parents in June
His family will chant to give thanks to pagan gods when the effects kick inStep-by-step explanation:
The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
