The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.670 g as required bymint specifications. The sample size is n= 36 and the test statistic is t= - 3.334. Use technology to findhativ the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10.hals, Begin by using the original claim to identify the null hypothesis and the alternative hypothesis for this test.The null hypothesis (denoted by Ho) is a statement that the value of a population parameter (suchas proportion, mean, or standard deviation) is equal to some claimed value. The alternativehypothesis (denoted by H, or Ha or HA) is a statement that the parameter has a value that somehow differsfrom the null hypothesis.

Given that Sample size n =36 Population mean =5.670 Test statistic t =-3.334

A safety administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in hic (standard head injury condition units). The safety requirement is that the hic measurement should be less than 1000 hic. Use a 0.05 significance level to test the claim that the sample is from a population with a mean less than 1000 hic. Do the results suggest that all of the child booster seats meet the specified requirement? 670 603 1014 534 501 662 What are the hypotheses? .

The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is n = 911 and the test statistic is t= 56.944. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.01.
