Aleasing firm claims that the mean number of miles driven annually, , in its leased cars is less than miles. a random sample of cars leased from this firm had a mean of annual miles driven. it is known that the population standard deviation of the number of miles driven in cars from this firm is miles. assume that the population is normally distributed. is there support for the firm's claim at the level of significance?
perform a one-tailed test. then fill in the table below.
carry your intermediate computations to at least three decimal places, and round your responses as specified in the table. (if necessary, consult a list of formulas.)
h0=
h1=
type of test statistic (z, t,chi-square, f)
the value of the test statistic(round to three decimals at least)
the critical value at the 0.05 level of significance (round to three decimal)
can we support the leasing firms claim that the mean number of mile driven annually is less than 13340 miles?
yes or no

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
