What type of procedure should we use, t or z?

A entomologist is analyzing the venom of worker bees. She would like to know if the average histamine content is greater than 300 nanograms. The following is data on histamine content in nanograms from 7 eight day old worker bees: 649, 832, 418, 530 , 384, 899, 755.

A) One sample z test for a mean

B) One sample t test for a mean

C) A matched pairs t test for the mean difference

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

don't report but were is the digram

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
