Assume that a hypothesis test to reject the given claim will be conducted. Identify the type I or type II error for the test. A cereal company claims that the mean weight of the cereal in its packets is 14 oz. Identify the type I error for the test. - Reject the claim that the mean weight is 14 oz when it is actually greater than 14 oz. - Fail to reject the claim that the mean weight is 14 oz when it is actually different from 14 oz. - Reject the claim that the mean weight is 14 oz when it is actually 14 oz. - Reject the claim that the mean weight is different from 14 oz when it is actually 14 oz.

The display provided from technology available below results from using data for a smartphone​ carrier's data speeds at airports to test the claim that they are from a population having a mean less than 4.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. LOADING...

Help please week 12

An electrician wants to know whether batteries made by two manufacturers have significantly different voltages. The voltage of 120 batteries from each manufacturer were measured. The population standard deviations of the voltage for each manufacturer are known. The results are summarized in the following table. Manufacturer Sample mean voltage (millivolts) Population standard deviati A 145 5 144 3 What type of hypothesis test should be performed?| v Select Right-tailed t-test Two-tailed z-test What is the test statistic? Ex: 0.12 € Right-tailed z-test Two-tailed t-test Does sufficient evidence exist to support the claim thiai it vuitayt ui it valieries made Select O Tat by the two manufacturers is different at the a 0.1 significance level?

Also need to find the standardized test statistic, decide whether to reject or fail to reject, and interpret the decision in the context of the claim.

Please answer all parts except f

State the null and alternative hypotheses for the statistical test described below. Your answer should be an expression composed of symbols: =,≠,<,>,μ,μ1,μ2,p,p1,p2,0.3,ρ,p^,p^1,p^2,r.Testing to see if there is evidence that a proportion is greater than 0.3.   H0:        vs Ha:

Please help me find the standardized test statistic and the P-value
