The shear strength of each of ten test spot welds is determined, yielding the following data (psi):409, 389, 402, 374, 362, 358, 375, 367, 415, 376Suppose we decide to examine another test spot weld. Let \( X \) = shear strength of the weld. Use the given data to obtain the MLE of \( P(X \leq 400) \). [Hint: \( P(X \leq 400) = \Phi \left( \frac{400 - \mu}{\sigma} \right) \).] (Round your answer to four decimal places.)You may need to use the appropriate table in the Appendix of Tables to answer this question.

From given data we have :409, 389, 402, 374, 362, 358, 375, 367, 415, 376.x=sher strength of the…

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below. Height (cm) of President 185 170 179 191 194 179 9 Height (cm) of Main Opponent 170 184 174 166 194 182 Identify the test statistic. t= 0.57 (Round to two decimal places as needed.) Identify the P-value P-value = 0.286 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is greater than the significance level, fail to reject the null hypothesis. There is not sufficient evidence to support the claim that presidents tend to be taller than their opponents. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)?

Assume k and w are the number of clasees and the width, respectively, of an equal width grouped FDT. If the lower limit of the first class (LL₁) equals the smallest observation in the corresponding dataset (whose measurement unit is 10 P, p= 0, 1, 2,...), (based on the way to construct an equal width grouped FDT taught in class) which of the followings best estimates the largest observation of the dataset? Select one or more: ULK LL₁ + (k-1)w kw LL₁ + (k+ 1)w LL₁+kw - 10 P LL₁ + kw

The determination of the shear strength of spot welds is relatively difficult, whereas measuring the weld diameter of spot welds is relatively simple. As a result, it would be advantageous if shear strength could be predicted from a measurement of weld diameter. The data are as follows: Shear strength (psi) Weld diameter (0.0001 in) 370 400 780 800 1210 1250 1560 1600 1980 2000 2450 2500 3070 3100 3550 3600 3940 4000 3950 4000 a) Test the hypothesis that the slope of the regression line is equal to 1 at the 0.05 level of significance.
