Answer:

see the procedure

Step-by-step explanation:

we know that

To find out the percentage of each type of treat, divide the number of each treat by the total number of treats and multiply by 100

The total number of treats is equal to

(40+15+10)=65

Percentage of candy bars

$\frac{40}{65} (100)=61.54\%$

Percentage of pieces of gum

$\frac{15}{65} (100)=23.08\%$

Percentage of lollipops

$\frac{10}{65} (100)=15.38\%$

Answer:

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

(11,688.68 , 12,511.32)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 17

mean of the sample x⁻ = 12,100

Standard deviation of the sample (S) = 800

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

Step(ii):-

Degrees of freedom ν =n-1 = 17-1 =16

$t_{(16 , 0.05)} = 2.1199$

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

$(12,100 - 2.1199\frac{800}{\sqrt{17} } , 12,100 + 2.1199 \frac{800}{\sqrt{17} } )$

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)

A term life policy was offered to your spouse for $3.49 per $1,000.00. You want him to have $100,000.00 coverage, what is the pr

ruslelena [56]

Answer:

The premium is $349 per year

Step-by-step explanation:

We can easily solve this problem by applying a rule of three

$3.49 ---------------------------------------- $1000 coverage

x ---------------------------------------- $100,000 coverage

By using this relation, we can find how much money is needed to pay

x = ($100,000/$1000)*$3.49

x = (100)*$3.49

x = $349

The premium is $349 per year
