As a project site civil engineer, you will evaluate the production and process of the concrete producers. You will find that whether the concrete is too watery or not. From the data, the contract specification state that the slump for the concrete used should be 1 inch, with a 90% level of confidence(hint: this is redundant given). So, we will take 10 random samples of fresh concrete and measure the slump. Data: 0.95 1.21 1.03 1.10 1.01 0.99 0.89 0.97 1.01 0.99 Test the hypothesis that mean concrete is different from 1 inch at 10% or 0.10 level of significance. HINT: t-test: two-tailed test.
