Average expiration duration of a dairy product is 22.6 hours with a standard deviation of 2.6 hours. If expiration durations are approximately normally distributed, determine: a)The probability that expiration duration is between 20.5 hours and 22.5 hours b) The duration that separates the top 30% of the duration from the bottom of the 70% of the duration. Round answer to one decimal place. c) If 36 samples of the product are randomly selected, what is the probability that the mean of their expiration duration is greater than 22.3 hours?
tainties (a) the mean heating value and (b) a single measurement of the heating value. 7.29 The following information about a linear submersible depth pressure transmitter is available: Range 0-20 m H$_2$O Output 4-20 mA Accuracy (including linearity, hysteresis, and repeatability) 0.2% Span Zero balance 2% Span Thermal effects 1.5% Span (a) What will be the nominal output of the device (in mA) at a depth of 15 m of water? (b) Estimate the uncertainty due to each of the error sources that can be determined from the specifications. Express the uncertainties in mA, in m H$_2$O, and as a percentage of the reading. (c) Calculate the total output uncertainty in mA, in m H$_2$O, and as a percentage of the output.
(1 point) Regarding y as the independent variable and x as the dependent variable, find the slope of the tangent line, i.e. find $\frac{dx}{dy}$ since y is the independent variable in this case, to the curve $4y^4 + 3x^2y^2 + 5yx^4 - 4y = 92$ at the point (2, 1). The slope of the tangent line to the curve at the point (2, 1) is
