Heights were measured for a random sample of plants grown while being treated with a particular nutrient. the sample mean and sample standard deviation of those height measurements were centimeters and centimeters, respectively. assume that the population of heights of treated plants is normally distributed with mean . based on the sample, can it be concluded that is different from centimeters? use the level of significance.
perform a two-tailed test. then fill in the table below. carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (if necessary, consult a list of formulas.)h0 : ? h1: ? the type of statistic (z, t, chi-square, or f)the value of the test statistic: round to at least three decimalsthe p-value (round to at least 3 decimals)at the 0.05 level of significance can it be concluded that the population mean height of treated plants is different from 40 centimeters? yes or no

These question are hard can you me with answers

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).
