Brut [27]

The answer would be C. You’re correct! Because there are 3 blue marbles @ $1 each that amounts to a possible $3 gain for Mark. Evan has the chance to get $4. Cayla also can make $3 like Mark.

The Lylian is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be an
nalin [4]

Answer:

p_v =P(z>z_{calc})

In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need  enough evidence in favor of the alternative hypothesis, so then the best option would be:

f. 0.001

Step-by-step explanation:

We need to conduct a hypothesis in order to test the claim that one of several methods claimed to increase the likelihood of a baby girl so then the system of hypothesis are:  

Null hypothesis:p\leq 0.5  

Alternative hypothesis:p > 0.5  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The p value for this case is given by:

p_v =P(z>z_{calc})

In order to establishing the success of the method we need to obtain a p value very low in order to reject the null hypothesis because we need  enough evidence in favor of the alternative hypothesis, so then the best option would be:

f. 0.001

Howard cuts 54 centimeters off of a 1- meter board. how much of the board does Howard have left?
OLEGan [10]
There are 100 centimeters in 1 meter, so 54 centimeters subtracted from 100 centimeters(1 meter) is 
100-54=46
so 46 centimeters remain, or 46/100 of the board which is really 23/50 of the board.
So basically, your possible answers:
46 centimeters
0.46 meters
46% of the original board
23/50 of the original board
