Start by simplifying, 10^2 = 100, 100*2.6 = 260    so for the other side we
 
10^11= 100000000000,  100000000000 times 3.9 = <span>390000000000 so for the

final answer we multiply the two numbers stop get a 

final answer of  </span>260 times 390000000000 = <span>1.014e+14</span>

64% of students will apply for graduate school. from a sample of 100 students, 52 stating that they will apply for grad school.
lana66690 [7]

Answer:

you<u> accept </u>the alternative hypothesis

Step-by-step explanation:

The null and alternative hypothesis can be computed as follows:

H_o: p = 0.64 \\ \\ H_1: p \le 0.64

The sample proportion \hat p = \dfrac{x}{n}

\hat p = \dfrac{52}{100}

\hat p = 0.52

The test statistics can be computed as:

Z = \dfrac{\hat p -p_o}{ \sqrt{ \dfrac{p_o \times (1-p_o)}{ n} }}}

Z = \dfrac{0.52 -0.64}{ \sqrt{ \dfrac{0.64 \times (1-0.64)}{ 100} }}}

Z = -2.5

The P-value = 2( Z< -2.5)

From the tables;

The P-value = 2 (0.0062)

The P-value = 0.0124

The significance level = 0.01

Since the P-value is > significance level; we fail to reject the null hypothesis.

Conclusion: we accept the alternative hypothesis
