What is 3/7 +1/5 and how would I get it<br>​
Aleks04 [339]

Answer:

22/35

Step-by-step explanation:

3/7 + 1/5

First, find a common denominator.

7*5=35  multiply the numerator by 5 too: 3*5=15

5*7=35  multiply the numerator by 7 too: 1*7=7

15/35 + 7/35

=22/35

Cannot be simplified.

A researcher wants to construct a 90% confidence interval for the proportion of elementary school students in Seward County who
dezoksy [38]

Answer:

The sample  size is  n =68

Step-by-step explanation:

    The population proportion is  \^ p =  0.50

     The margin of error is  E =  0.1

From the question we are told the confidence level is  90% , hence the level of significance is    

      \alpha = (100 - 90 ) \%

=>   \alpha = 0.10

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.645

Generally the sample size is mathematically represented as  

    n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )

=>  n = [\frac{1.645 }{0.1} ]^2 * 0.50  (1 - 0.50 )

=>  n =68
