This is because if she types 25 words in one minute then that means she can type 50 words in 2 minutes (just multiply by 2). The only person on the graph who can type 50 words in 2 minutes is Britt.

Hope this helps! Any questions let me know :)

Phantasy [73]

Answer:

\hat p \pm Z*\sqrt{\frac{\hat p\times(1-\hat p)}{n} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(1-0.5546)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(0.4454)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.2470}{458} }

=0.5546\pm1.96*\sqrt{0.00053934}

=(0.5091,0.6001)

Lower limit for confidence interval=0.5091

             

Upper limit for confidence interval=0.6001

Step-by-step explanation:

We have given,              

             

x=254          

n=458          

Estimate for sample proportion= \bar p = 0.5546

Level of significance is =1-0.95=0.05      

Z critical value(using Z table)=1.96      

Confidence interval formula is

\hat p \pm Z*\sqrt{\frac{\hat p\times(1-\hat p)}{n} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(1-0.5546)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.5546\times(0.4454)}{458} }

=0.5546\pm1.96*\sqrt{\frac{0.2470}{458} }

=0.5546\pm1.96*\sqrt{0.00053934}

=(0.5091,0.6001)

Lower limit for confidence interval=0.5091

             

Upper limit for confidence interval=0.6001
