Just before a referendum on a school budget, a local newspaper polls 402 voters to predict whether the budget will pass. Suppos

Sliva [168]

Answer:

21.21%

Step-by-step explanation:

Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.

Sample size(n)= 402

We know that standard deviation is given as

$\sigma = \sqrt {\dfrac {p(1-p)}{n}}$

Now by putting the values

$\sigma = \sqrt {\dfrac{0.52\times 0.48}{402}}$

σ=0.0249

Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249

We know that $Z=\dfrac{\bar{X}-\mu }{\sigma }$

$Z=\dfrac{0.5-0.52 }{0.0249}$

Z= -0.80

So P(Z<-.80) =0.2118 from standard table.

So the probability of news paper to predict defeat is 21.21%

You have invested $2000 at 3.75% annual interest. How much money do you have after 20 years?

lbvjy [14]

Answer:

$3500

Step-by-step explanation:

Let's use PRT/100 to see what will be the total amount.

Total amount = Interest + Principle

Solution:

PRT/100 = Interest
=> 2000 x 3.75 x 20 years/100
=> 20 x 3.75 x 20 = Interest
=> 2 x 2 x 375 = Interest
=> 4 x 375 = Interest
=> 1500 = Interest
=> Total amount = 1500 + 2000
=> Total amount = $3500

Hence, after 20 years, the amount earned is $3500.
