If your solving for m it is m=-4n+ 9 and if you’re solving for 9 it’s -1/4m+9/4

Alex Ar [27]

This question is incomplete, the complete question;

The American Psychological Associated conducted a survey in 2003 of psychologists to estimate the average incomes for psychologists based on their academic degree and years of experience. 36 psychologists responded who had a just received their masters degree in 2003. The average was $48,800 with a standard deviation of $16,800.

The 95% Confidence Interval is ($, $ )

Answer:

at 95%, confidence interval is ( $43312, $54288 )

Step-by-step explanation:

Given the data in the question;

sample size n = 36

mean x' = 48,800

standard deviation σ = 16,800

at 95% confidence level;

∝ = 1 - 95% = 1 - 0.95 = 0.05

∝/2 = 0.05 / 2 = 0.025

z critical value, Z_{\alpha/2 = 1.96

now, confidence interval for population mean is given by the formula

x' ±  Z_{\alpha/2( σ/√n )

so we substitute

⇒ 48800 ±  1.96( 16800/√36 )

⇒ 48800 ±  1.96( 2800 )

⇒ 48800 ±  5488

⇒ 48800 -  5488, 48800 +  5488

⇒ ( 43312, 54288 )

Therefore, at 95%, confidence interval is ( $43312, $54288 )

A market buys watermelons for $1.25 they want to make a 20% profit what should they charge for the watermelons
Serhud [2]

Answer: $1.50

Step-by-step explanation:

Cost price of watermelon = $1.25

Profit percent = 20%

Profit = Profit percent × Cost price

= 20% × $1.25

= 20/100 × $1.25

= 0.2 × $1.25

= $0.25

Selling price = Cost price + Profit

Selling price = $1.25 + $0.25

Selling price = $1.50

They should charge $1.50 for the watermelons
