# In a random sample of 6 cell phones, the mean full retail price was \$525.10 and the standard deviation was \$177.00. Further research suggests that the populationmean is \$432.82. Does the t-value for the original sample fall between -to gg and to gg? Assume that the population of full retail prices for cell phones is normallydistributedThe t-value of tfall between to g9 and to gg because to g9 =.990.99(Round to two decimal placess as needed.)

I'm not sure what t-value is in order so solve for it.

Step 1

The t-distribution is used, because the population standard deviation is unknown and the sample standard deviation is being used as a substitute.

Calculation:

Here, n = 6;  = 525.10; s = 177.00.

There...
