Answer:

-\frac{35}{8} or -4\frac{3}{8}

Step-by-step explanation:

N + \frac{3}{8} = -4 : Move constant to the right-hand side and change its sign.

N = -4 - \frac{3}{8} : Calculate the difference.

N = -\frac{35}{8}

(Alternative form: -4\frac{3}{8}, -4.375)

Sergeeva-Olga [200]

Answer:

6.76

Step-by-step explanation:

Let us create hypothesies as

H_0: p =0.50\\H_a: p>0.50

(right tailed test for claiming most adults would erase)

Sample proportion p = 0.64

n = sample size = 582

Std error of proportion= \sqrt{\frac{0.5*0.5}{582} } \\=0.0207

P difference = 0.14

Test statistic = p difference/std error

= 6.755

=6.76
