Answer:

y = 1/5x - 6/5

Step-by-step explanation:

Step 1: Write out known variables

m = 1/5

y = 1/5x + b

Step 2: Find <em>b</em>

-1 = 1/5(1) + b

-1 = 1/5 + b

b = -6/5

Step 3: Write linear equation

y = 1/5x - 6/5

Yakvenalex [24]

Answer: E= 0.107

Step-by-step explanation:

Formula to find the margin of error : E=z^*\sqrt{\dfrac{p(1-p)}{n}}

, where n= sample size .

p= sample proportion

z* = critical value.

Given : Sample size : n= 62

Number of red candies out of 62 =  15

Proportion of red candies = p=\dfrac{15}{62}\approx0.242

We know that , the critical value for 95% confidence = z*= 1.96  [Using z-table]

Then,

E=(1.96)\sqrt{\dfrac{0.242(1-0.242)}{62}}

E=(1.96)\sqrt{\dfrac{0.242(0.758)}{62}}

E=(1.96)\sqrt{\dfrac{0.183436}{62}}

E=(1.96)\sqrt{0.00295864516129}

E=(1.96)(0.0543934293945)

E=0.106611121613\approx0.107

Hence, the margin of error = E= 0.107
