Suppose a geyser has a mean time between eruptions of 76 minutes. let the interval of time between the eruptions be normally distributed with standard deviation 27 minutes. (round everything to four decimal places)a) what is the probability that a randomly selected time interval between eruptions is longer than 87 minutes? b) what is the probability that a random sample of 14 time intervals between eruptions has a mean longer than 87 minutes? c) what is the probability that a random sample of 26 time intervals between eruptions has a mean longer than 87 minutes? d) what effect does increasing the sample size have on the probability? fill in the blanks with either increases or decreases. if the population mean is less than 87 minutes, then the probability that the sample mean of the time between eruptions is greater than 87 minutes because the variability in the sample mean as the sample size .e) what might you conclude if a random sample of 26 time intervals between eruptions has a mean longer than 87 minutes? choose the best answer. a) the population mean must be more than 76, since the probability is so low. b) the population mean is 76, and this is an example of a typical sampling result. c) the population mean must be less than 76, since the probability is so low. d) the population mean may be greater than 76.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

that is the sum

there are no other answers without knowing the variables values

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.
