A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a 0.10 significance level to test the claim that the four categories are equally likely.

Systolic blood pressure levels above 120 mm Hg are considered to be high. For the 100 systolic blood pressure levels listed in the accompanying data set, the mean is 120.48000 mm Hg and the standard deviation is 15.73549 mm Hg. Assume that a simple random sample has been selected. Use a 0.05 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg. Click the icon to view the data set of systolic blood pressure levels. Identify the null and alternative hypotheses. ▼ Ho: H₁: (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis. There ▼sufficient evidence at the 0.05 significance level to C than 120 mm Hg. the claim that the sample is from a population with mean systolic blood pressure level greater
