Please answer C,D and 3. ty!~ Newly purchased tires of a particular type are supposed to be filled to a pressure of 30 psi. Let u denote the true average pressure. A test is to be carried out to decide whether μ differs from the target value.Determine the P-value for each of the following z test statistic values. (Round your answers to four decimal places.)(a) 2.170.0300(b) -1.730.0836(c) -0.51(d) 1.45(e) -4.10USE SALT The desired percentage of SiO₂ in a certain type of aluminous cement is 5.5. To test whether the true average percentage is 5.5 for a particular production facility, 16 independently obtained samples are analyzed.Suppose that the percentage of SiO2 in a sample is normally distributed with = 0.32 and that x = 5.24. (Use α = 0.05.)(a) Does this indicate conclusively that the true average percentage differs from 5.5?State the appropriate null and alternative hypotheses.OH: μ = 5.5Ha: μ< 5.5O Ho: μ = 5.5Ha: μ ≥ 5.5O Ho: μ = 5.5H₂:μ # 5.5O Ho: μ = 5.5Hg: μ > 5.5

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula).
