A study published in Psychiatry Research states that 62% of autistic children are left-handed.[12]
nordsb [41]

Answer:

The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.

Step-by-step explanation:

Test if there is enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research:

This means that at the null hypothesis we test if the proportion is 62%, that is:

H_0: p = 0.62

At the alternate hypothesis, we test if the proportion is different from 0.62, that is:

H_a: p \neq 0.62

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample

62% is tested at the null hypothesis:

This means that \mu = 0.62, \sigma = \sqrt{0.62*0.38}

When a random sample of 26 autistic children were observed, 17 were found to be left-handed.

This means that n = 26, X = \frac{17}{26} = 0.6538

Value of the test statistic:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{0.6538 - 0.62}{\frac{\sqrt{0.62*0.38}}{\sqrt{26}}}

z = 0.36

Pvalue of test and decision:

The pvalue of the test is the probability of a proportion that differs from the mean by at least 0.6538 - 0.62 = 0.0338, which is P(|z| > 0.36), which is two multiplied by the pvalue of z = -0.36

Looking at the z-table, z = -0.36 has a pvalue of 0.3594

2*0.3594 = 0.7188

The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.

mojhsa [17]

Answer:

y = 4/3x + 6

Step-by-step explanation:

y = 4/3x + b

2 = 4/3(-3) + b

2 = -4 + b

6 = b

y = 4/3x + 6

A 450-square-foot apartment in new york city costs $540,00 what is the price per square foot?
alex41 [277]

Answer:

$1200

Step-by-step explanation:

Let cost of 1 square foot be x

So, Cost of 450 square feet =  450x

We are given that A 450-square-foot apartment in New York City cost $540,000.

So, 450x = 540000

x= \frac{540000}{450}

x= 1200

Cost of 1 square foot = $1200

Hence the price per square foot is  $1200
