Hii, this geometry, please help haha!!

its 6

Step-by-step explanation:

(16x+5) = 1

50 - 45 = 5

5+1=6

The test statistic for this hypothesis test =1.597

Step-by-step explanation:

When population standard deviation is unknown, we use t-test statistic:

= sample mean, = population mean , s= sample standard deviation, n = sample size.

As per given,

Hence, the test statistic for this hypothesis test =1.597
