Mathematics
1 answer:
Lena [83]3 years ago
3 0

Answer:

Step-by-step explanation:

a). 1\frac{3}{5}=1+\frac{3}{5}

         =1+\frac{3}{5}\times \frac{4}{4}

         =1+\frac{12}{20}

         =1\frac{12}{20}

   1\frac{3}{4}=1+\frac{3}{4}

        =1+\frac{3}{4}\times \frac{5}{5}

        =1+\frac{15}{20}

        =1\frac{15}{20}

Therefore, common denominator of 20.

b). 2\frac{1}{2}=2+\frac{1}{2}

         =2+\frac{1}{2}\times \frac{5}{5}

         =2+\frac{5}{10}

         =2\frac{5}{10}

     \frac{4}{5}=\frac{4}{5}\times \frac{2}{2}

        =\frac{8}{10}

Common denominator of 10.

c). \frac{3}{8}=\frac{3}{8}\times \frac{6}{6}

       = \frac{18}{48}

   \frac{1}{6}=\frac{1}{6}\times \frac{8}{8}

      = \frac{8}{48}

Common denominator of 48.

In a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less. A local man cl
Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Given that in a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less.

The sample size n = 80

no of wells less than 100 feet deep=27

Sample proportion = \frac{27}{80} =0.3375

a) Create hypotheses as

H_0: p = 0.30\\H_a: p >0.30\\

(Right tailed test)

p difference = 0.3375-0.30 = 0.0375

Std error of p = \sqrt{\frac{0.3(0.7)}{80} } =0.0512

b) Assumptions: Each trial is independent and np and nq >5

c) Z test can be used.

Z= p diff/std error = \frac{0.0375}{0.0512} =0.73

p value = 0.233

d) p value is the probability for which null hypothesis is false.

e) Conclusion: Since p >0.05 we accept null hypothesis

there is no statistical evidence which support the claim that more than 30% are drilled.
