Answer:

Please check the explanation.

Step-by-step explanation:

Given

$P(Z > 1.96)$

To determine

What probability expression is equivalent to $P(Z > 1.96)$ .

Suppose Z is a standard normal variable.

Therefore,

P(Z > 1.96) = 1 - P(Z ≤ 1.96)

solving

= 1 - Ф(1.96)

$= 1 - 0.9750$

$= 0.0250$

n 2018, homes in East Baton Rouge (EBR) Parish sold for an average of $239,000. You take a random sample of homes in Ascension p

Olenka [21]

Answer:

Conclusion

There is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Step-by-step explanation:

From the question we are told that

The population mean for EBR is $\mu_ 1 = \$239,000$

The sample mean for Ascension parish is $\= x_2 = \$246,000$

The p-value is $p-value = 0.045$

The level of significance is $\alpha = 0.01$

The null hypothesis is $H_o : \mu_2 = \mu_1$

The alternative hypothesis is $H_a : \mu_2 > \mu_1$

Here $\mu_2$ is the population mean for Ascension parish

From the data given values we see that

$p-value > \alpha$

So we fail to reject the null hypothesis

So we conclude that there is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Order decimals from least to greatest .. 1.09, 1.901,1.9,1.19

Nuetrik [128]

The easiest way to do this is to write the decimals with equal amount of places after the dot and you'll see it more clearly:

1.09 = 1.090
1.901 = 1.901
1.9 = 1.900
1.19 = 1.190

So from the least to the greatest:

1.090
1.190
1.900
1.901

In a form you gave at the beginning:

1.09 < 1.19 < 1.9 < 1.901

the population of a town was 650000. Due to an epidemic,the population of the town went down by 12%.Find the current population

Dimas [21]

Answer:

572000

Step-by-step explanation:

The population reduced by 12%, so (100-12)=88% is remaining.

So, 88% of 650000= 0.88 x 650000

= 572000
