Answer:

actually it is a dreivative of y which is an transversal of iys equation but as you shown y=-7. the error might be in negative there should be a probability of it. Thanks for asking a question

Answer:

There is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

Step-by-step explanation:

From the question we are told that

The population mean is less than 1.5

The sample size is n = 7

The sample data is 2, 0, 1, 5, 0, 2, and 3

Generally the sample mean is mathematically represented as

$\= x = \frac{ \sum x_i }{ n }$

=> $\= x = \frac{ 2 + 0 + 1 + 5 + 0 + 2 + 3 }{ 7 }$

=> $\= x = 1.857$

Generally the standard deviation is mathematically represented as

$\sigma = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }$

=> $\sigma = \sqrt{\frac{ (2 - 1.857)^2 + (0 - 1.857)^2 +\cdots (3 - 1.857)^2}{7} }$

=> $\sigma = 1.773$

The null hypothesis is $H_o : \mu = 1.5$

The alternative hypothesis is $H_a : \mu < 1.5$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }$

=> $z = \frac{\= x - 1.857 }{ \frac{1.773 }{\sqrt{7} } }$

=> $z = 0.53$

Generally the p-value is mathematically represented as

$p-value = P(z < 0.53 )$

From the z-table

$P(z < 0.53 ) = 0.70194$

$p-value = 0.70194$

From the values obtained we see that $p-value > 0.05$

Here there is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5

If 5 students went in cars then 216 students were in the buses (221-5=216)

There were four buses so divide 216 by 5 which is 54.

So there were 54 students in each bus
