150 parents were surveyed. 26% said that the kids were noddy and 70% said their kids were nice. How many parents didn't answer w

alexandr1967 [171]

Answer:

The parents who didn't answer with either naughty and nice are 6.

Step-by-step explanation:

Given:

150 parents were surveyed. 26% said that the kids were naughty and 70% said their kids were nice.

Now, to find parents who didn't answer with either naughty and nice.

So, as given in question:

70% said that their kids are naughty.

26% said that their kids are nice.

So, to get the percentage of parents who didn't answer we subtract.

Thus, the percentage of parents who didn't answer with either naughty and nice:

100% - (70% + 26%)

100% - 96% = 4%.

Hence, 4% of parents didn't answer.

Now, to get how many parents didn't answer we calculate the percentage of the total who didn't answer:

Total parents surveyed = 150.

Parents who didn't answer = 4% of the total parents surveyed.

$Parents\ who\ didn't\ answer = 4\% of 150.$

$Parents\ who\ didn't\ answer = \frac{4}{100}\times 150.$

$Parents\ who\ didn't\ answer = \frac{600}{100}.$

$Parents\ who\ didn't\ answer = 6.$

Therefore, the parents who didn't answer with either naughty and nice are 6.

Solve for y: 2½y = ⅝ Answer in simplest form.

MrMuchimi

Step-by-step explanation:

$2 \frac{1}{2} y = \frac{5}{8}$

Convert Mixed number to improper fraction.

$2 \frac{1}{2} = \frac{5}{2}$

Equate

$\frac{5}{2} y = \frac{5}{8}$

Cross Multiply

$5y \times 8 = 2 \times 5 \\ 40y = 10$

Divide both sides of the equation by 40

$\frac{40y}{40} = \frac{10}{40}$

Simplify

$y = \frac{1}{4}$

A recent poll of 700 people who work indoors found that 278 smoke. if the researchers want to be 98% confident of their results

Mice21 [21]

Answer:

We are given:

$\hat{p}=\frac{278}{700}=0.397$

$z_{\frac{0.02}{2}}=2.33$ is the critical value at 0.02 significance level

$E=0.035$ is the margin of error

Therefore, the required sample size is:

$n=\hat{p}(1-\hat{p}) \left(\frac{z_{\frac{0.02}{2}} }{E} \right )^{2}$

$=0.397(1-0.397) \left( \frac{2.33}{0.035} \right)^2$

$=0.239391 \times 4431.755102$

$=1060.922286 \approx 1061$

Therefore, the required sample size n = 1061
