### Watermelon Crop Pricing AnalysisUnderstanding the market price for watermelon crops is essential for farmers to make informed decisions. This exercise details how to find confidence intervals and required sample sizes for price estimation.**Scenario**: In the third week of July, a random sample of 43 farming regions gave a sample mean price $ \bar{x} = \$6.88 $ per 100 pounds of watermelon. The standard deviation $ \sigma $ is known to be \$1.90 per 100 pounds.#### (a) 90% Confidence Interval for Population Mean PriceCalculate a 90% confidence interval for the population mean price (per 100 pounds) that farmers receive for their watermelon crop. Determine the margin of error. Record your answers to two decimal places.- **Lower Limit**: $____- **Upper Limit**: $____- **Margin of Error**: $____#### (b) Sample Size for Maximal ErrorDetermine the sample size necessary for a 90% confidence level with a maximal error of estimate $ E = 0.39 $ for the mean price per 100 pounds of watermelon. The sample size should be rounded up to the nearest whole number.- **Sample Size**: ____ farming regions#### (c) Confidence Interval for Market Cash ValueA farm brings 15 tons of watermelon to market. Calculate a 90% confidence interval for the population mean cash value of this crop. Note: 1 ton equals 2000 pounds. Round your answers to two decimal places.- **Lower Limit**: $____- **Upper Limit**: $____- **Margin of Error**: $____These calculations help in understanding the variability and expected range of market prices for the watermelon crops, thereby aiding in agricultural economics and decision-making processes.

You have obtained the number of years of education from one random sample of 38 police officers from City A and the number of years of education from a second random sample of 30 police officers from City B. The average years of education for the sample from City A is 15 years with a standard deviation of 2 years. The average years of education for the sample from City B is 14 years with a standard deviation of 2.5 years. Is there a statistically significant difference between the education levels of police officers in City A and City B?What is the appropriate test for this case? 2 sample z-testChi-square test 2-sample t-test2 sample paired t-test Carry out the test.
