Answer:

0.25

Step-by-step explanation:

Average means \frac{total \: number}{number \:  \: of  \: \: individuals}

According to the formula, each student in Mr. Goldwasser's class read

\frac{66}{24}  = 2.75

books on average, and each student in Mr. Welch's class read

\frac{65}{26}  = 2.5

books on average.

Therefore, the answer will be

2.75 - 2.5 = 0.25

What is the surface area of the rectangular prism?<br> lenth 16 with 4 and hight 4
Llana [10]

Answer:

272

Step-by-step explanation:

The formula is 2(LxW) + 2(LxH) + 2(WxH)

2(16 x 4) = 128

2(16 x 4) = 128

2(4 x 4) = 16

16 + 128 + 128 = 272

A researcher obtains t = 2.35 for a repeated-measures study using a sample of n = 8 participants. Based on this t value, what is
ZanzabumX [31]

Answer:

p_v =2*P(t_{7}>2.35)=2*0.0255=0.051  

If we compare the p value and using the significance level given \alpha=0.05 we have p_v>\alpha so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% or 1% of significance we fail to reject the null hypothesis.

Step-by-step explanation:

It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  

The significance level is not provided but we can assume it as \alpha=0.05. First we need to calculate the degrees of freedom like this:

df=n-1=8-1=7

The next step would be calculate the p value for this test.  Since is a bilateral test or two tailed test, the p value would be:  

p_v =2*P(t_{7}>2.35)=2*0.0255=0.051  

If we compare the p value and using the significance level given \alpha=0.05 we have p_v>\alpha so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% or 1% of significance we fail to reject the null hypothesis.
