Answer:

b=−1/14ot+2

Step-by-step explanation:

Let's solve for b.

to−8+5b=−6+26−9b

Step 1: Add 9b to both sides.

ot+5b−8+9b=−9b+20+9b

ot+14b−8=20

Step 2: Add -ot to both sides.

ot+14b−8+−ot=20+−ot

14b−8=−ot+20

Step 3: Add 8 to both sides.

14b−8+8=−ot+20+8

14b=−ot+28

Step 4: Divide both sides by 14.

14b

−ot+28

−1

ot+2

A town has a population of 32,000 in the year 2002; 38,400 in the year 2003; 46,080 in the year 2004; and 55,296 in the year 200

The point is to find the growth rate. The compound formula is:

P=A(1+ growth rate)ⁿ, where A is the initial Value & P the new value after n years:
P₂₀₀₃ =P₂₀₀₂ (1+ growth rate)¹ (the period "n" from 2002 to 2003 being 1 year)

38400 = 32000(1+growth rate)¹
38400 / 32000 - 1= growth rate & growth rate = 1/5 = 0.2
You will balso find the same growth rate for:
P₂₀₀₄ = P₂₀₀₃(1+ growth rate)¹
P₂₀₀₅ = P₂₀₀₄((1+ growth rate)¹
between 2015 & 2002 THERE ARE 14 YEARS:

P₂₀₁₅ = P₂₀₀₂(1+0.2)¹⁴ & P₂₀₁₅ = 32000(1+02)¹⁴ = 410,854

Can you conclude with a high degree of confidence that the population means for Iowa and New Jersey students are different? A.

Complete Question

The complete question is shown on the first uploaded image

Answer:

Option A is correct

Step-by-step explanation:

From the question we are told that

The 95% confidence interval of the mean score of all New Jersey third graders is (58.957 , 63.043)

The sample size is n = 184

The sample average is $\mu = 65 \ points$

The standard deviation is $\sigma = 13 \ points$

The 90% confidence interval for the difference in mean score between lowa and New Jersey is (-6.33 , -1.67 )

The p-value is $p-value = 0.0048$

Generally given that the p-values is very low compared to the level of significance (100 -90 = 10% = 0.10 ) we can reject the null hypothesis which is usually a claim that the means of the population are the same )

Hence the population means are different .
