CD Camera produces a new camera that it claims can take an average of at least 7 photographs per second. A test of 49 randomly selected cameras found a sample mean of 6.8 photos/sec. The population standard deviation is known to be 0.58 photos/sec.

Does the sample data present sufficient evidence to reject the manufacturer's claim? If so, how strong is the evidence? Use a hypothesis testing procedure and an alpha = 0.01. Be sure to clearly state the null and alternate hypothesis using proper notation.

  • Rejecting a Claim

    The population standard deviation is known to be 0.65 photos/sec. Does the sample data present sufficient evidence to reject the manufacturer's claim? If so, how strong is the evidence? Use a hypothesis testing procedure and an alpha = 0.01.

  • How do you test a manufacturer's claim that defective machines are not a fluke of a sample?

    The manufacturer claims this is a fluke of the sample. At a 0.01 level of significance, test the manufacturer's claim and explain your answer.

    A complete, neat and step-by-step solution is provided to determine whether we can reject the manufacturer's claim based on the data.

  • Hypothesis test for a population proportion

    Value of test statistic: -0.3666 p value: 0.357 Since p-value is greater than 0.05 so we fail to reject null hypothesis. Thus we cannot reject the manufacturer's claim at the .05 level of significance.

  • Sample Standard Deviation for Automobile Manufacturer
