Can someone help me to find length CD
uysha [10]

Answer:

CD = 3.602019190339

Step-by-step explanation:

CD = DA - CA

DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507

BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278

CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168

Then

CD = 16.355388523507 - 12.753369333168 = 3.602019190339

A psychologist is interested in knowing whether adults who were bullied as children differ from the general population in terms
MissTica

Answer:

t = \frac{39.5-30.6}{\frac{6.6}{\sqrt{25}}}= 6.74

The degrees of freedom are given by:

df =n-1= 25-1=24

Now we can calculate the p value with the following probability:

p_v = 2*P(t_{24}>6.74)= 5.69x10^{-7}

And for this case since the p value is lower compared to the significance level \alpha=0.05 we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05

Step-by-step explanation:

For this case we have the following info given:

\bar X = 39.5 represent the sample mean

s =6.6 represent the sample deviation

\mu = 30.6 represent the reference value to test.

n = 25 represent the sample size selected

The statistic for this case is given by:

t =\frac{\bar X -\mu}{\frac{s}{\sqrt{n}}}

And replacing we got:

t = \frac{39.5-30.6}{\frac{6.6}{\sqrt{25}}}= 6.74

The degrees of freedom are given by:

df =n-1= 25-1=24

Now we can calculate the p value with the following probability:

p_v = 2*P(t_{24}>6.74)= 5.69x10^{-7}

And for this case since the p value is lower compared to the significance level \alpha=0.05 we can reject the null hypothesis and we can conclude that the true mean for this case is different from 30.6 at the significance level of 0.05
