Answer:

The $p-$ value is $0.2996$ .

Step-by-step explanation:

This is a right-tailed test.

The null and alternative hypothesis is

$H_0:p=0.60\\H_a:p>0.60$

Point estimate $=$ sample proportion $=\hat{P}=x/n=0.630$

Test statistics

$z=\left(\hat{p}-p_{0}\right) / \sqrt{p}_{0^{*}}\left(1-p_{0)} / n\right.$\\$=(0.630-0.60) / \sqrt{(0.60 * 0.40) / 73}$\\$=0.526$\\P-value $=P(Z>z)$\\$=0.2996$\\The $\mathrm{P}$ -value is $0.2996$

Answer:

arc axb=4.938

Step-by-step explanation:

to find the measure of arc AXB find angle P first

length of the arc=rФ

in triangle APQ sin angle APQ= opp/hyp=AQ(radius)/PQ=5/√5+√21

in traingle PQB sin angle BPQ= opp/hyp.=5/√5+√21

angle P"

2arcsin 5/√5+√21= 94.324 degrees=(π*94.324)/180=1.64626 rad.

arc AXB=Фr (Ф=94.324 , r=3)

arc axb=4.938
