Identify test statisticIdentify p-valuerestate the decision in simple, nontechnical terms, and address the original claim. Listed in the data table are amounts of strontium-90 (in millibecquerels, or mBq, per gram of calcium) in a simple random sample of baby teeth obtained from residents in two cities. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use a 0.10 significance level to test the claim that the mean amount of strontium-90 from city #1 residents is greater than the mean amount from city #2 residents.**Click the icon to view the data table of strontium-90 amounts.**---What are the null and alternative hypotheses? Assume that population 1 consists of amounts from city #1 levels and population 2 consists of amounts from city #2.- **A.** $ H_0: \mu_1 = \mu_2 $ $ H_1: \mu_1 \neq \mu_2 $- **B.** $ H_0: \mu_1 = \mu_2 $ $ H_1: \mu_1 > \mu_2 $ (Selected)- **C.** $ H_0: \mu_1 \neq \mu_2 $ $ H_1: \mu_1 > \mu_2 $- **D.** $ H_0: \mu_1 \leq \mu_2 $ $ H_1: \mu_1 > \mu_2 $The test statistic is [____]. (Round to two decimal places as needed.) The table presents numerical data comparing two cities, labeled as City #1 and City #2. Each city has a list of numerical values. These could represent various measurements, such as temperature, population, sales, etc. The data is as follows:**City #1:**- 101- 86- 121- 110- 101- 104- 213- 143- 290- 100- 262- 145**City #2:**- 117- 71- 100- 85- 83- 107- 110- 111- 102- 133- 101- 209This comparison could be used to analyze patterns, differences, or similarities between the two cities based on the values presented.

USE 3 DECIMAL A producer claims that his potato chips weight has a normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams. If manager want to test the claim as night shift mean weight of the product is greater than that of day shift at 1% level of significance. Calculate the test statistics.
